Application Guidelines
Conducted noise on the input power lines ca n occur
as either differential-mode or common-mode noise
currents. Dif ferential-mode noise is measured
between the two input lines, and is found mostly at
the low frequency end of the s pec trum. This noise
shows up as nois e at the fundamental switchi ng
frequency and its har monics . Com mon-mode noise is
measured bet ween the input lines and ground an d i s
mostly broadband nois e above 10 MHz. The high-
frequency natu r e of common-mode noise is mostly
due to the high-s peed switching t ransitions o f power
train compone nts. Either or both types of noise may
be covered in a specif i cation, as well as a
combination of the two.
Differential-mode noise is best attenuated using a
filter composed of line-to-line capacitors (X ca ps) and
series inductance, provided by either a discrete
inductor or t he l eak age inductance of a common-
mode choke. In addition to the di fferential f i ltering
provided by th e filter module, it is recom m ended that
an electrolyt ic capacitor be located at t he converter
side of the filter to provide additional att enuation of
low-frequenc y different i al noise and to provide a low
source impedance for the converter, preventing input
filter oscillations and load transient in duced input
voltage dips.
Open-frame DC/DC converter m odul es and the older
metal-cased DC/DC converter modules requ ire
slightly different filt ering arrangements. The
FLT007A0Z s eries of modules are optimized for the
newer open-frame series of modules , but can also be
used with older metal-case modules. The main
differences i n filtering recommendat ions between the
two types of modules are in common-mode filtering,
as explained b el ow.
Filtering Open-Frame DC/DC
Converter Modules
For filtering open-frame DC/DC converter modules,
the recommended circuit is s hown in Fig. 5. In
addition to the input electrolytic filt er capacitor C1
(recommende d value is a minimum of 100uF and
approximate ly 1uF/W at power levels above 100W),
common-mode filtering c apacitors C2 and C3 should
be connected between the in put and outputs as
shown. Suitable valu es for common-mode capacitors
C2 and C3 are in the r ange bet ween 1 000pF to 0.1µF
are usually indicated in the DC/DC converter data
sheet. Thes e c apacitors need to be rated for the
isolation vo ltage desired between the inp ut and output
sides of the DC/ DC c onverter module. The
recommended power layout of the modules showing
where the two common-mode capacitor s are to be
placed is shown in Fig. 6.

Filtering Metal-Case DC/DC Converter
Modules
For metal-case DC/DC convert er modules with a c ase
pin, a different filtering ar r angement and l ayout is
recommended. Figure 7 show s the schematic
diagram of the recommended circuit. The main
difference with open-frame module is the use of an
isolated shi eld plane locat ed underneath the module
which is connected through capacitors C 2 through C5
to the input and output connections of the module.
The shield plane along with t he case of the module
serves as a Faraday shield he l ping reduce EMI. The
corresponding layout for m etal-case modules is
shown in Fig. 8.

Figure 9 shows example results obtained using a
QBE025A0B1 DC/DC converter module with the
FLT007A0Z filter module. The QBE025A0B1 module
is operated at an input voltage of 43.2V and out put
loading corresponding to an input current of 6.2A, a
level close to t he 7A capability of the FLT007A 0Z filter
module. A 10n F ceramic capac itor was connected
between Vin( -) and Vo(-) and a 470 0pF ceramic
capacitor between Vin(+) and V o(+). The r esult s show
that the filter module is capable of meeting EN55022

Thermal Considerations
Power modules operate in a variety of thermal
environment s; however, s ufficient cool ing should
always be prov ided to help ensure reliable o per ation.
Considerati ons include am bient temper ature, airflow,
module power dissipatio n, and the need for increased
reliability. A reductio n in the operating temperatur e of
the module will result in an increase in reliabilit y. The
thermal data presented her e is based on phy sical
measurements taken in a win d tunnel. The test set-
up is shown in F i g. 10. Note that t he airflow is parallel
to the long axis of the module as s hown in Fig. 10.

Post solder Cleaning and Drying
Considerations
Post solder cl eaning is usually the final circuit-board
assembly process prior to electrical board testing. The
result of inadequate cleaning and drying c an affect
both the relia bi lity of a power module and the
testability of the finish ed circuit-board assembly. For
guidance on appr opriate soldering, cleaning and
drying procedures, refer to Lineage Power Board
Mounted Power Modules: S oldering and Cleaning
Applicatio n Note.
Through-Hole Lead-Free Soldering
Information
The RoHS-co m pl iant through-hole product s use the
SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant
components. They are designed to be process ed
through single or dual wave sol dering machi nes. The
pins have an R oH S-compliant finish that is compatible
with both Pb a nd Pb-free wave s ol dering proc es ses.
A maximum preheat rate of 3°C/s is suggested. The
wave preheat pr ocess should be such that the
temperature of the power mod ule board is ke pt below
210°C. For Pb solder, the recommen ded pot
temperature is 260°C, while the Pb-free solder pot is
270°C max. Not all RoHS-co m pl iant through-hole
products can be processed with paste-through-hole
Pb or Pb-free reflow process. If addit ional information
is needed, please consult with your Linea ge Power
representative for more details.
Surface Mount Informati on
Pick and Place
The FLT007A0-SRZ SMT modules use an open
frame construction and are d esigned for a f ully
automated assembly process . The modules are fitted
with a label designed to prov ide a large surface area
for pick and place operations . The label meets all the
requirements for surface mount processing, as well as
safety standards, and is able to withstand reflow
temperatures of up to 300oC. The label also carries
product information such as product code, serial
number and lo c ation of manufacture.
Nozzle Recommendati on s
The module weight has been kept to a minimum by
using open frame construct ion. Even so, t hese
modules have a relativel y large mass whe n c ompared
to conventional SMT components. Variables such as
nozzle size, tip style, vacuum pressure and pick &
placement sp eed should be considered t o optimize
this process. The minimum recom mended nozzle
diameter for reliable operation is 5mm. The maximum
nozzle outer d iameter, which will safely fit within the
allowable component spaci ng, is 8 mm max.
Tin Lead Soldering
The FLT007A0-SRZ power modu les are lead free
modules and can be soldered ei ther in a lead-free
solder process or in a conventional Tin/Lead (Sn/Pb)
process. It i s recommended that the customer review
data sheets in order to customize the solder reflow
profile for eac h applicatio n board assembly. The
following ins tructions mus t be observed when
soldering these units. Fail ur e to observe these
instructio ns may result in t he failure of or cause
damage to the modules, and can adv er sel y aff ect
long-term relia bility.
In a conventional Tin/Lead (Sn/Pb) solder process
peak reflow temperatures are limited to les s than
235oC. Typical ly, the eutectic solder melts at 183oC,
wets the land, and subsequent ly wicks the dev i c e
connection. Sufficient time must be allowed to f us e
the plating on the connection to ensure a reli able
solder joint . There are sever al types of SMT r eflow
technologies currently used in the industry. These
surface mount power modules can be reliably
soldered using natural for c ed convection, IR (radiant
infrared), or a combination of convection/IR. For
reliable soldering the sol der reflo w prof i le should be
established by accurate ly measuring the modules CP
connector tem peratures.

Storage and Handling
The recommended storage environment and handling
procedures for moisture-s ensitive surf ace mount
packages is detailed in J-STD-033 Rev. A (Handling,
Packing, Shipping and Us e of Moisture/Reflow
Sensitive Sur face Mount Devices). Moi s ture barrier
bags (MBB) with desiccant are required for MSL
ratings of 2 or greater. Thes e s eal ed packages
should not be brok en until time of use. Once the
original package is broken, the floor life of the product
at conditions of <= 30°C and 60% relative hu midity
varies according to the MSL rating (see J -STD-033A).
The shelf lif e for dry packed SM T packages will be a
minimum of 12 months from the bag seal dat e, when
stored at the following conditions: < 40° C, < 90%
