Description
The FME270 Series EMI filters are specifically designed to
reduce the reflected input ripple current of Interpoint’s high
frequency DC/DC converters. FME270 filters minimize electro-
magnetic 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.
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 compo-
nents. 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 applica-
tions. 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 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.
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:
OpeRatIOn OveR teMpeRatuRe
The FME270-461 Series filters are rated for full power opera-
tion 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
FME270-461 filters are sealed in metal hermetic side-leaded
packages. See cases U, V, W, Y, and Z.
