FME28-461 EMI Input Filters
28 Volt Input – 15 Amp
Features
Attenuation to 60 dB at 500 kHz
• Operating temperature -55° to +125°C
• Nominal 28 V input, 0 to 50 V operation
• Transient rating to ±100 V for 100 ms
• Up to 15 A throughput current
• Compliant to MIL-STD-461C, CE03
• Compatible with MIL-STD-704 A-E 28 VDC power bus
Description
The FME Series™ EMI filters are specifically designed to reduce
the reflected input ripple current of Interpoint’s high frequency
DC/DC converters. FME filters minimize electromagnetic interference (EMI) for the MOR, MFL, MTR, MHV, MHF+, MHF, MTO
and MHE Series of converters. These filters are intended for
use in 28 volt applications which must meet MIL-STD-461C
CE03 levels of conducted emissions. One filter can be used with
multiple converters up to the rated output current of the filter.
Input Ripple and EMI
Switching DC/DC converters naturally generate two noise
components on the power input line: differential noise and
common mode noise. Input ripple current refers to both of these
components. Differential noise occurs between the positive input
and input common. Most Interpoint converters have an input filter
that reduces differential noise which is sufficient for many applications. Common mode noise occurs across stray capacitances
between the converter’s power train components and the baseplate (bottom of the package) of the converter.
Where low noise currents are required to meet MIL-STD-461C,
a power line filter is needed. The FME28 EMI power line filters
reduces the common mode and differential noise generated by
the converters. FME28 filters reduce input ripple current by as
much as 60 dB at 500 kHz and 1 MHz when used in conjunction
with Interpoint’s DC/DC converters.

Place the filter as close as possible to the converter for optimum
performance. The baseplates of the filter and the converter
should be connected with the shortest and widest possible
conductors.
Transients
A transient of -100 to +100 V for up to 100 ms with a 0.5 ohm
source impedance will not damage the filter but will be passed on
to the converter:
Operation over Temperature
The FME28-461 Series filters are rated for operation from -55°C
to +125°C case temperature.
Insertion Loss
The maximum dc insertion loss at full load and nominal input
voltage represents a power loss of less than 4%.
Packaging
FME28-461 filters are sealed in metal hermetic side-leaded packages. See cases U, V, W, Y, and Z.

The case ground connection between the filter and the converter should be as
low an impedance as possible to minimize EMI. Direct contact of baseplate to

SLAM™/C-SAM:
Input capacitors only
(Add’l test, not req. by H)
Notes:
1. Standard and /ES, non-QML products, do no meet all of the requirements of
MIL-PRF-38534.
2. M/S = Active components (Microcircuit and Semiconductor Die)
3. P = Passive components
4. Not applicable to EMI filters that have no wire bonds.
Definitions:
Element Evaluation: Component testing/screening per MIL-STD-883 as determined by MIL-PRF-38534
SLAM™: Scanning Laser Acoustic Microscopy
C-SAM: C - Mode Scanning Acoustic Microscopy
