Description
The FMCE-0828TM EMI filters are specifically designed to reduce the reflected input ripple current of Interpoint's high frequency DC/DC converters. FMCE-0828 filters minimize electromagnetic interference (EMI) for the MFL, MOR, MTR, MHV and MHF+ Series of converters. These filters are intended for use in 28 volt applications which must meet MIL-STD-461C CE03 and CS01 and/or MIL-STD-461D, E and F CE102 and CS101 levels of conducted emissions. One filter can be used with multiple converters up to the rated output current of the filter.
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.
tRansIents
A transient of -0.5 to 80 V (0.5 ohm source impedance) will not damage the filter but will be passed on to the converter:
Input RIpple and eMI
OpeRatIOn OveR teMpeRatuRe
Switching DC/DC converters naturally generate two noise components 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-461C and/or CE102 of ML-STD-461D, E and F, a power line filter is needed. The FMCE-0828 EMI power line filters reduce the common mode and differential noise generated by the converters. FMCE-0828 filters reduce input ripple current by 60 dB, typical, at 500 kHz and 1 MHz when used in conjunction with Interpoint's DC/DC converters.
The FMCE-0828 Series filters are rated for full power operation from -55C to +125C case temperature. Current is derated linearly to 80% at +135C case temperature.
InseRtIOn lOss packagIng
The maximum dc insertion loss at full load and nominal input voltage represents a power loss of less than 3%. FMCE-0828 filters are sealed in metal hermetic, down-leaded packages non-flanged (case F5) or flanged (case J6). Also available in a side-leaded package (case U).

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.
