DESCRIPTION

TRANSIENT SUPPRESSION

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.

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.
