DESCRIPTION
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.
These filters are built using thick-film hybrid technology and are
sealed in metal packages for military, aerospace, and other high-
reliability applications. See Section B8, cases H3, H5, K4, and K6
for dimensions. See Section C2 for screening options.
MIL-STD N
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 perform-
ance of a model MHE2805S converter with and without the FM-461
filter is shown in Figures 6 and 7.

F
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 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.
L
The case of the filter must be connected to the case of the converter
through a low impedance connection to minimize EMI.
