DESCRIPTION

The filter must be placed 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 conduc-

tors. For the best connection, mount the filter’s and converter’s

baseplates on or above a small ground plane.

The SFME28-461™ Series EMI filter modules are specifically

designed to reduce the reflected input ripple current or ripple voltage

of high frequency DC/DC converters. SFME28-461 filters minimize

electromagnetic interference (EMI) for Interpoint’s space applica-

tions converters. These filters are intended for use in 28 volt appli-

cations which must meet MIL-STD-461 levels of conducted emis-

sions. One filter can be used with multiple converters up to the rated

output current of the filter.

OPERATION OVER TEMPERATURE

All SFME28-461 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.

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.

INSERTION LOSS

The maximum dc insertion loss at full load and nominal input voltage

represents a power loss of less than 4%.

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 most applications.

PACKAGING

SFME28-461filters are sealed in metal hermetic side-leaded pack-

ages.

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 conducted noise currents or voltages are required to

meet CE03 of MIL-STD-461C or CE102 of MIL-STD-461D, a power

line filter is needed. The SFME28-461 Series of EMI power line

filters reduces the common mode and differential noise generated

by the converters. SFME28-461 filters reduce input ripple current by

a minimum of 60 dB at 500 kHz and 1 MHz when used in conjunc-
