See screening table for more information. Description The, 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-61C 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 highreliability applications. See Section B8, cases H, H, K, and K6 for dimensions. See Section C2 for screening options. Filter Operation A fast-reacting (1 picosecond) transient suppressor clamps the input voltage at approximately 7 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 C to +8 C (as measured at the baseplate). Above 8 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 % at typical input voltage. MIL-STD Noise Management When used in conjunction with Interpoint s DC/DC converters (see connection diagram, Figure 2), the input ripple current will be reduced by 0 db within the frequency band of 100 khz to 0 MHz. This gives the filter/converter combination a performance which exceeds the CE0 test limit of MIL-STD-61C. The CE0 performance of a model MHE280S converter with and without the FM-61 filter is shown in Figures 6 and 7. Layout Requirements The case of the filter must be connected to the case of the converter through a low impedance connection to minimize EMI.
