DESCRIPTION
The FMC-461™ and SFMC EMI filters have been specifically
designed to reduce the input line reflected ripple current of
Interpoint’s MHF, MTR, MTO, MHV, MHF+, MHD, MTW, MHE, and
MLP series of DC/DC converters including their space counterparts.
The filter can be used to filter combinations of the lower power
converters up to two MTR/SMTR series converters and a single
MFL/SMFL series converters. They are intended for use in applica-
tions which have high frequency switch-mode DC/DC converters
and which must meet MIL-STD-461C or MIL-STD-461C levels of
conducted and radiated noise.
The FMC/SFC filters are built using thick-film hybrid technology and
is hermetically sealed in metal packages for military, aerospace, and
other high-reliability applications. The filters use only ceramic
capacitors for reliable high temperature operation.

ONLY
The FMC-461 filter also features an optional fast-reacting (1 pico
second) transient suppressor (transorb) which begins clamping the
input voltage at approximately 47 VDC, protecting the DC/DC
converter from damage from induced line transients.
The FMC-461NT does not have the transorb option.

EMPERATURE
The filters are rated to operate, with no degradation of performance,
over the temperature range of -55°C to +125°C (as measured at the
baseplate). Above +125°C, current must be derated as specified on
the following page.

NSERTION

OSS
The maximum DC insertion loss for the FMC/SFMC filters (at a load
of 22 watts) represents a power loss of less than 2% at typical input
voltage.

ANAGEMENT
When used in conjunction with Interpoint converters, the FMC-461,
FMC-461 NT and SFMC-461 filters reduce input ripple current within
the frequency band of 100 kHz to 50 MHz. This gives the
filter/converter combination a performance which exceeds the
CEO3 test of MIL-STD-461C and the CE102 test of MIL-STD-461D.
Typical FMC-461 filter frequency response and output impedance
behavior are shown in Figures 4 and 5. CEO3 performance of a
typical converter with the FMC-461 filter connected is shown in
Figure 3.

EQUIREMENT
The case pin, and ideally the case, should be tied to the case of the
converter through a low-inductance connection.

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 chassis ground provides the lowest impedance.
