Bolt Style EMI Filters
SA Series – 4-40 Thread - Epoxy Sealed –
Circuits Available – C & L
The SA series provides effective filtering
in the RF and MICROWAVE frequency
spectrums from 10 MHz through 26 GHz.
Designed for mounting in a tapped
bulkhead or with the standard nut and
lockwasher provided, it is ideal for high
impedance circuits where large capaci-
tance values are not practical. In the “L”
section version an internal ferrite bead
element provides both inductance and
series resistance (lossy characteristic)
which improves insertion loss and pro-
vides superior transient performance. The
SA series comes with a standard .020
diameter beryllium copper lead. Alternate
lead lengths, diameters of .016 or .026
and alternate materials in steel or half-
hard copper are available.
• Meets or exceeds the applicable portions
of MIL-F-28861/6. See QPL listings.
• Smallest screwbody filter available.
• Features rugged monolithic discoidal
capacitor construction.
• Epoxy seal on both ends.
1. Plating: Silver standard – Electro-tin or
gold available
2. Material:
Case: Cold rolled steel
Leads: Beryllium copper (steel or half/hard
copper leads available)
3. Operating Temperature Range:
-55°C to +125°C
4. Insulation Resistance:
At 25°C: 1,000 megohm-microfarad
min., or 100,000 megohms
min., whichever is less
At 125°C: 100 megohm-microfarad
min., or 10,000 megohms
min., whichever is less
5. Dielectric Withstanding Voltage (DWV):
R-level designs:
2.0 times rated DC voltage
Class B, Class S designs:
2.5 times rated DC voltage
6. DC Resistance (DCR): .02 ohm,
maximum
7. Dissipation Factor (DF): 3% maximum
8. Rated DC Current: 5 Amps, maximum
9. Recommended Mounting Torque:
32 oz-in. ± 4 oz-in.
10. Supplied with mounting nut and lock-
washer - See Filter Design Guide Screw
and Locking Washer Table
11. Insertion Loss for the “C” and “L” sections
are equivalent due to the saturation
characteristic of the ferrite bead element
at rated current. At lower currents the “L”
becomes much more effective.

Notes:
1. Standard catalog designs
have .020" dia. lead. MIL-F-
28861/6 calls for .026" dia.
.026" dia. will not be supplied
unless specified.
2. “A” dimension of .120 ± .005
will satisfy M28861/6-003
requirement for .145 ± .030.
All “SA” series are supplied
A = .120 ± .005.
3. All SA2 L-Section Filters have
inductor (bead) at threaded
end.
