Description
The FMCE-0528™ EMI filters have been specifically designed to
reduce the input line reflected ripple current of Interpoint’s MTR,
MHF+, and MHV series of DC/DC converters. The filter can be
used with combinations of the lower power converters; up to two
MTR series converters or a single MFL series converter. 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.
The FMCE-0528 filters are built using thick-film hybrid tech-
nology and are hermetically sealed in metal packages for military,
aerospace, and other high-reliability applications. Only ceramic
capacitors are used in the filters to ensure reliable high tempera-
ture operation.
The filters are offered with standard screening, “ES” screening,
or fully compliant to “883” MIL-PRF-38534 Class H screening.
Standard microcircuit drawings (SMD) are available.

The FMCE-0528-TR filter also features an optional fast-reacting
(1 pico second) transient suppressor (transorb) which begins
clamping the input voltage at approximately 47 VDC, protecting
the DC/DC converter from damage from induced line transients.
The FMCE-0528 does not have the transorb and is designed for
those applications that require a wider input voltage range (0 to
50 V).

The filters are rated to operate, with no degradation of perfor-
mance, over the temperature range of -55°C to +125°C (as
measured at the baseplate). Above +125°C, current must be
derated as specified on the following page.

Low DC resistance design results in a maximum power loss of
less than 3% with typical input voltage.
When used in conjunction with Interpoint converters, the FMCE-
0528 and FMCE-0528-TR filters reduce input ripple current
within the frequency band of 100 kHz to 50 MHz. When used
with an Interpoint converter, performance exceeds the CEO3
test of MIL-STD-461C and meets the requirements of CS01 of
MIL-STD-461C. These filters also meet CE102 and CS101 of
MIL-STD-461D, E and F.

Notes
1. guaranteed by design, not tested.
2. The FMCE-0528 does not have a transorb and does not clamp the
input voltage
3. 0.5 ohm source impedance
4. Typical applications result in Vout within 2% of Vin.
