Description
Filter Operation
These filters are built using thick-film hybrid technology and are
sealed in metal packages for military, aerospace, and other highreliability applications. See Section B8, cases H3, H5, K4, and
K6 for dimensions. See Section C2 for screening options.
The filters are rated to operate, with no degradation of performance, over the temperature range of –55°C to +85°C (as
measured at the baseplate). Above 85°C, input voltage and
current must be derated as specified in “Derating” on the
following page. The maximum power dissipation of the filters at
maximum input current represents a power loss of less than 3%
at typical input voltage.
MIL-STD Noise Management
Layout Requirements
The FM-461, FMA-461, and FMB-461 EMI filter modules have
been specifically designed to reduce the input line reflected ripple
current of Interpoint’s MTO, MTW, MHE, MLP, and MFW Series
of DC/DC converters. They are intended for use in applications of
high frequency (100 kHz) switch-mode DC/DC converters which
must meet MIL-STD-461C levels of conducted power line noise.
When used in conjunction with Interpoint’s DC/DC converters
(see connection diagram, Figure 2), the input ripple current will
be reduced by 40 dB within the frequency band of 100 kHz to 50
MHz. This gives the filter/converter combination a performance
which exceeds the CE03 test limit of MIL-STD-461C. The CE03
performance of a model MHE2805S converter with and without
the FM-461 filter is shown in Figures 6 and 7.

A fast-reacting (1 picosecond) transient suppressor clamps
the input voltage at approximately 47 V, protecting the DC/DC
converter from line induced transients.
The case of the filter must be connected to the case of the
converter through a low impedance connection to minimize EMI.

The case ground connection should be as low an impedance as possible to minimize EMI.
