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 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 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 performance of a model MHE2805S converter with and without the FM-461 filter is shown in Figures 6 and 7. FILTer operaTIoN 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 perfor- mance, 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. LayouT requIreMeNTS The case of the filter must be connected to the case of the converter through a low impedance connection to minimize EMI.
