DESCRIPTION
The FMC-461™ EMI filter has 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. It is intended for use in applications which have high
frequency switch-mode DC/DC converters and which must meet
MIL-STD-461C levels of conducted and radiated noise.
TRANSIENT SUPPRESSION
The FMC-461 filter also features a fast-reacting (1 pico second)
transient suppressor which begins clamping the input voltage at
approximately 47 VDC, protecting the DC/DC converter from
damage from induced line transients.
OPERATING TEMPERATURE
The FMC filter is built using thick-film hybrid technology and is
hermetically sealed in metal packages for military, aerospace, and
other high-reliability applications. The filter uses only ceramic
capacitors for reliable high temperature operation.
The filter is 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.
MIL-STD NOISE MANAGEMENT
INSERTION LOSS
When used in conjunction with Interpoint converters, the FMC-461
filter reduces input ripple current by 40 dB within the frequency band
of 200 kHz to 50 MHz. This gives the filter/converter combination a
performance which exceeds the CEO3 test of MIL-STD-461C.
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.
The maximum DC insertion loss for the FMC-461 filter (at a load of
22 watts) represents a power loss of less than 2% at typical input
voltage.
LAYOUT REQUIREMENT
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.
