1 / 16 page MODELS INPUT VOLTAGE AND CURRENT B3-7 Input (V) 28 28 270 270 Current ( A) 7.0 15.0 0.7 1.5 DESCRIPTION The FMD Series™ and FME Series™ EMI filters are specifically designed to reduce the reflected input ripple current of Interpoint’s high frequency DC/DC converters. FMD/FME filters minimize elec- tromagnetic interference (EMI) for the MHE, MHL, MLP, MRH, MTO, MHF, MHF+, MHV, MHD, MTR, MFL, MHP, and MFLHP Series. These filters are intended for use in 28 or 270 volt applications which must meet MIL-STD-461C, CE03 levels of conducted emis- sions. One filter can be used with multiple converters up to the rated output current of the filter. INPUT RIPPLE AND EMI Switching DC/DC converters naturally generate two noise compo- nents on the power input line: differential noise and common mode noise. Input ripple current refers to both of these components. Differential noise occurs between the positive input and input common. Most Interpoint converters have an input filter that reduces differential noise which is sufficient for many applications. Common mode noise occurs across stray capacitances between the converter’s power train components and the baseplate (bottom of the package) of the converter. Where low noise currents are required to meet CE03 of MIL-STD- 461, a power line filter is needed. The FMD/FME Series of EMI power line filters reduces the common mode and differential noise generated by the converters. FMD/FME-461 filters reduce input ripple current by as much as 60 dB at 500 kHz and 55 dB at 1 MHz when used in conjunction with Interpoint’s DC/DC converters. See Figures 8 and 9. Place the filter as close as possible to the converter for optimum performance. The baseplates of the filter and the converter should be connected with the shortest and widest possible conductors. For the best connection, mount the filter’s and converter’s baseplates on or above a small ground plane. See Figure 5. TRANSIENTS The transients listed below will not damage the filter but will be passed on to the converter: • All filters: ±600 volts (50 ohm source impedance) for up to 10 µs. • 28 volt filter: ±100 volts (0.5 ohm source impedance) for up to 100 ms. • 270 volt filter: ±500 volts (independent of source impedance) for up to 100 ms. OPERATION OVER TEMPERATURE All FMD/FME-461 Series filters are rated for full power operation from –55°C to +125°C case temperature. Current is derated linearly to zero at +135°C case temperature. INSERTION LOSS The maximum dc insertion loss at full load and nominal input voltage represents a power loss of less than 4%. PACKAGING FMD/FME-461 filters are sealed in metal hermetic side-leaded packages. See Section B8, cases U1, U2, V, W, Y, and Z. Additionally the FMD28-461 filter is available in a metal hermetic down-leaded package (see Section B8, case J4). LAYOUT REQUIREMENTS The case of the filter must be connected to the case of the converter through a low impedance connection to minimize EMI.
