The Amphenol® EMI lter connector utilizes two manufacturing
technologies to provide the user with the most cost effective
performance across the frequency range. (For EMP perfor-
mance data, see pages 172-175).
The tubular design offers over 40 years of proven eld
reliability. All lter contacts within the connector share a
common ground plane, which is connected to the connector
shell. The pin to pin isolation is 85 dB minimum at 100 MHz.
The planar design joins pins to a multi-layered ceramic forming
an array sub-assembly, with a peripheral ground which is
connected to the connector shell via a ground spring. Pin to
pin capacitance is less than 50 pf with a pin to pin isolation of
85 dB minimum at 100 MHz. Filter contacts for both designs
contain either a pi passive ele ment network comprised of a
ferrite inductor and ceramic capacitor, or a single capacitor.
For planar designs other lter networks are available, ie.
T Type, L-C Type, C-L Type and C Type. An encapsulant of
oven-cured epoxy in the rear provides:
Mechanical and thermal insulation of the ceramic •
elements – mechanical loading can be accomplished
without capaci tor damage. Pins can be bent 90° and
straightened with no damage to the lter.
Hermeticity (4.6 x 10• -3 cc/sec) – prevents water from
enter ing through the rear of the connector in high
humidity envi ronments. Amphenol recommends using
metal protection caps during cleaning operations.

Amphenol provides a wide range of ltering solutions. You
can select your options for your particular interference
threats - VHF, UHF, HF or other lter ranges, then couple
with a connector package of your choice. Or give Amphe nol
your custom shell design requirements for assistance in
designing your unique lter solution.
EMI Filter connectors are intended for use in temperatures
from –55°C to +125°C. Attenuation will change with feed-
through current and temperature.*
To assure reliability, connectors may be subjected to an
attenuation performance test verifying proper assembly and
grounding of the lters. Attenuation data on lter per-
formance is stated in reference to a 50 ohm impedance
system in order to allow lter performance to be more
eas ily translated into real world impedances. Those inter-
ested in determining the expected lter perfor mance in an
impedance system other than 50 ohms may refer to page
131 of this catalog or may contact Amphenol Aerospace for
further assistance.
It is suggested that the user analyze his system
require ments for EMI protection in the following areas:
Working voltage (DC or AC and Frequency)•
Peak voltage•
Desired attenuation at a given frequency level• Any special capacitance limitations•
Definition of Filter Contacts:
MF-1 Medium Frequency
50 dB performance between 300 - 2999 KHz
HF-1 High Frequency
50 dB performance between 3 - 29 MHz
VHF-1 Very High Frequency
50 dB performance between 30 - 2999 MHz
UHF-1 Ultra High Frequency
50 dB performance between 300 - 2999 MHz
Filter contacts can be provided in most frequencies in
con tact sizes 22 or larger. Consult Amphenol Aerospace
for availability.
Tubular connector designs will meet 3 amps RF current
from –55°C through +125°C. Planar connector designs
will meet 5 amps.
Planars, MOV’s, Tubular and Diode Contacts
Contact Options
Coaxial, concentric twinax, triax and quadrax contacts can be •
included in arrangements of ltered contacts for signal or power
circuits (See Amphenol catalog 12-130, High Frequency
Contacts for Multi-Pin Connectors).
Filter contacts with differing cut-off frequencies can be mixed in •
any given insert arrangement. (ratio 100:1 typical)
Ground, insulated or lter contacts can be combined within the •
same connector to meet unique or changing frequency
protec tion requirements.

Adapters
Filter adapters eliminate replacement of either existing mated pair. The
adapter provides the circuit protection at the MF, VHF and UHF levels,
and is an effective and economical method of introducing EMI/EMP
pro tection to an installed system. Adapters are to be placed between
mating faces. (See pages 171).
Printed Circuit Board Mount
Receptacle shell modications that allow mounting directly to a PC board
or ex header. Stand-off shells are available in different congurations.
These offer improved reliability by eliminating external spacers and
wash ers. (See pages 140, 141, 146, 147,160 and 163).
Hermetic
The hermetic lter connector, while only approximately 1/2 inch longer
than standard series connectors, provides all the benets of a hermetic
connector, plus EMI protection for sensitive circuits. The lter assembly is
protected by a fused glass insert within a unique steel housing. This design
provides the capability to tolerate high level static pressure while
maintaining a low level leakage rate. Consult Amphenol Aerospace for
more information.
Composite
Composite shell lter connectors meet the MIL-DTL-38999, Series III
dimensional length, and offer a light-weight, corrosion resistant, durable
connector with the same high performance features as its metal counter-
part. The composite lter connector utilizes planar technology to
accom modate VHF-1 or better electrical performance characteristics.
(See pages 138-141).
ESD Protection
Filter connectors with ESD (Electrostatic Discharge) protection are
avail able. These MIL-DTL-38999 Series I and III connectors have an added
feature of a Faraday Cage to shunt electrostatic discharge events to the
conduc tive enclosure on which the con-
nector is mounted.
(See page 203).
Filtered Plugs
Filtered Plugs are designed for
applications where EMI protection is
essential, but access to the receptacle
is denied. Designed with the same com-
ponents as a standard lter receptacle,
the ltered plug offers the option of being
mounted on the cable harness. It is a cost effective method of achiev-
ing EMI protection when length restrictions prohibit
inclusion of an adapter to the system. Consult Amphenol
Aerospace for availability.
Diode Connectors
Diode Connectors offer versatility with transient protection for sensi-
tive circuits, such as TTL lines. Diodes can stand alone or be com-
bined with other lters. (Pages 174-175).
Filter Adapters can be attached to connectors to
provide EMI/EMP protection.
Cylindrical Filter Protection Connectors are offered
in a wide range of styles, with custom designs for
special applications.

The following formula and example are offered in order to
deter mine the expected filter performance in an impedance
system other than 50 ohms.
With the attenuation expressed in 50 ohms and the transfer
impedance curve shown in Figure 1 below, a designer can relate
the expressed attenuation to the input and output imped ance of
his circuit.
Example:
(1) Noise is 40dB above specication level at 100 MHz
(2) Input and output impedance are 10 and 100 ohms
respectively
(3) Amphenol® VHF 7000 pf lter has a 65 dB minimum
attenuation at 100 MHz and +25°C
Formula (Taken from Figure 1):
1.4 x 10-2= transfer impedance
for 65 dB in a 50 ohm system
Atten (dB) = 20 log10 1 +
ZS = source impedance
ZL = load impedance
Z12 = transfer impedance
Atten = filter performance in a system other than 50 ohms
Atten (dB) = 20 log10 1 +
Attenuation = 56.3dB
In this case, the 7000 pf VHF lter will give 56.3 dB which is
16.3dB below the desired reduction in noise (40dB) as stated
in the above problem.

A plug with a given rotation letter will mate with a
receptacle with the same rotation letter. The AB angle for a
given connec tor is the same whether it contains pins or
sockets. Inserts are not rotated in conjunction with the
master key/keyway.
AB angles shown are viewed from the front face of the
connec tor. A receptacle is shown at right. The angles for the plug
are exactly the same, except the direction of rotation is opposite
of that shown for the receptacle.

A plug with a given rotation letter will mate with a recep-
tacle with the same rotation letter. The AB angle for a
given connec tor is the same whether it contains pins or
sockets. Inserts are not rotated in conjunction with the
master key/keyway.
AB angles shown are viewed from the front face of the
connec tor. A receptacle is shown at right. The angles for
the plug are exactly the same, except the direction of
rotation is opposite of that shown for the receptacle.

the same rotation letter. The AB angle for a given connector is
the same whether it contains pins or sockets. Inserts are not
rotated in conjunc tion with the master key/keyway.
AB angles shown are viewed from the front face of the
connector. A receptacle is shown at right. The angles for the plug
are exactly the same, except the direction of rotation is opposite
of that shown for the receptacle.

The Amphenol ® MOV Connector offers the versatility of a
stan dard connector, with transient protection for sensitive
circuits.Transients in electrical circuits caused by a sudden
release of stored energy can originate within or outside of the
circuit and may be repeatable or random.
Regardless of frequency or origin, transient caused failures
generated by load switching, lightning, electrostatic discharge
(ESD) and electromagnetic pulse (EMP) can destroy unpro-
tected IC components.
Compatible with present lter connector assembly
procedures, MOVs can be combined with existing lters.
Internal housing of the MOV offers weight and space savings
over other pro tection methods available today, and eliminates
costly and bulky exterior suppression mechanisms in
appropriate situations. MOVs are presently available in
contact sizes 22, 20 and 16.
Transient protection can be provided in receptacle, plug or
adapter conguration. These connectors are intermateable
and intermountable with the following MIL-Specs:

The Amphenol ® Energy Shunting Assembly (ESA) is a simple,
compact unit which provides lightning and electromagnetic pulse
(EMP) protection of systems in which many signal lines enter sensitive
electronic equipment. The efcient packaging of the ESA circumvents
the concept of one protective device per line. It provides a surge
arrestor which has the advantage of space sav ing and simplied
assembly when compared to current protective devices which range
from diodes to large spark gaps.
The current ESA design consists of two 53-pin contact,
Mil-Stan dard, hermetic connectors assembled back to back, and
encom passing a ground plate. A sealed chamber is formed within this
thru-bulkhead unit, housing 53 in-line spark gaps. Introducing a
controlled atmosphere enhances fast rise breakdown.
The ESA can be integrated with an EMI lter connector which can
improve its performance. These two assemblies provide a method to
help protect against lightning, EMP, EMI and TEM PEST effects.

The Hermetic Filter Connector
While only approximately 1/2 inch longer than standard series con nectors, the her-
metic lter connector provides all the benets of a her metic connector, as well as EMI
protection for sensitive circuits. The lter assembly is protected by a fused glass insert
within a unique steel housing. This design accounts for the connector’s capability
intolerating high level static pressure, while
maintaining a low level leakage rate.
Applications include pressurized test
equipment, environmental and toxic gas
chambers, and moisture sealing on
industrial equipment and missiles.
Filtered Plug
This connector is designed for
applications where EMI protection is
essential, but access to the receptacle
is denied. The ltered plug presents an
alternative for the electrical engineer.
The lter plug is designed with the same
components as a standard lter receptacle,
but offers the option of being mounted on the cable harness.
This device is a cost effective method of achieving
EMI protection when length restrictions
prohibit inclusion of an adapter to the system.
Filter Connectors can also incorporate high frequency coax,
twinax, triax, quadrax and differential twinax contacts.
Amphenol MIL-DTL-38999 Series III connectors are the most
com monly used connectors for incorporation of shielded
contacts along with traditional crimp contacts. High
performance shielded coaxial, twinax and triax contacts are
available to t various RG and special cables. They eliminate
discontinuities or impedance variations due to movement of
parts under axial load. Size 8 quadrax and differential twinax
contacts provide high speed data transfers.
Filter Connectors with Flex Termination
Flex circuits are available for MIL-DTL-38999, MIL-DTL-5015 and
MIL-DTL-26482 lter connectors. They are offered in at or sculptured
styles and provide exibility in assembling to printed circuit boards.
Through Amphenol’s Advanced
Circuit Technology division, these
strong and rigid, yet highly exible
circuits eliminate the need to
purchase and attach individual pins
or connectors. Thus they promote
system automation, reduce space
requirements and lower installation
costs. Sculptured® Flexible Circuits
have built-interminations which
eliminate the failure associated with
crimped or soldered-on contacts,
and geometrically t the tight space
requirements within a unit.
