1 / 13 page  Description The FME Series™ EMI filters are specifically designed to reduce the reflected input ripple current of Interpoint’s high frequency DC/DC converters. FME filters minimize electromagnetic interfer- ence (EMI) for the MOR, MFL, MTR, MHV, MHF+, MHF, MTO and MHE Series of converters. These filters are intended for use in 28 volt applications which must meet MIL-STD-461C CE03 levels of conducted emissions. 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 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 appli- cations. Common mode noise occurs across stray capacitances between the converter’s power train components and the base- plate (bottom of the package) of the converter. Where low noise currents are required to meet MIL-STD-461C, a power line filter is needed. The FME28 EMI power line filters reduces the common mode and differential noise generated by the converters. FME28 filters reduce input ripple current by as much as 60 dB at 500 kHz and 1 MHz when used in conjunction with Interpoint’s DC/DC converters. 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 -100 to +100 V for up to 100 ms with a 0.5 ohm source impedance will not damage the filter but will be passed on to the converter: OpeRatIOn OveR teMpeRatuRe The FME28-461 Series filters are rated for operation from -55°C to +125°C case temperature.
