FMe270-461 eMi input Filters
270 Volt input - 1.5 aMp
Features
* Operating temperature -55 to +125C * Transient rating to 500 V for 100 ms * Up to 1.5 A throughput current * Compliant to - MIL-STD-461C, CE03
attenuation to 50 dB at 500 kHz
* Nominal 270 V input, 0 to 400 V operation
Description
The FME270 SeriesTM EMI filters are specifically designed to reduce the reflected input ripple current of Interpoint's high frequency DC/DC converters. FME270 filters minimize electromagnetic interference (EMI) for the MHP270 Series of converters. These filters are intended for use in 270 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.
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 -500 to +500 V for up to 100 ms will not damage the filter but will be passed on to the converter:
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 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 MIL-STD-461C, a power line filter is needed. The FME270 EMI power line filters reduces the common mode and differential noise generated by the converters. FME270 filters reduce input ripple current by as much as 50 dB at 500 kHz and 55 dB at 1 MHz when used in conjunction with Interpoint's DC/DC converters.
OpeRatIOn OveR teMpeRatuRe
The FME270-461 Series filters are rated for full power operation from -55C to +125C case temperature. Current is derated linearly to zero 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 4%. FME270-461 filters are sealed in metal hermetic side-leaded packages. See cases U, V, W, Y, and Z.
