DESCRIPTION

he SFMC28-461™ EMI filters provide an off-the-shelf filtering solu-

tion compliant to MIL-PRF-38534, Class H or Class K, for use in

your space system. SFMC28-461 filters reduce the input line

reflected ripple current of Interpoint’s switching DC/DC converters.

Use an SFMC28-461 filter with Interpoint’s SMSA and SMHF series

of DC/DC converters to meet MIL-STD-461C levels of conducted

emission (CE01, CE03). The SFMC filters are designed exclusively

with passive components providing maximum tolerance for space

environments.

FILTER DESIGN

SFMC28-461 filters incorporate thick-film hybrid technology and use

only high quality ceramic capacitors for reliable high temperature

operation.

Derating according to the requirements of MIL-STD-975 assures

dependable performance in the harsh environments of space. MIL-

STD-975 derating applies to operating temperatures at or below

90°C.

The SFMC28-461 EMI filters offer the following options to meet the

special requirements of space applications:

All SFMC28-461 filters are built to the same assembly drawing

regardless of environmental screening or radiation tolerance level.

Filters designated level OO, indicating standard environmental

screening, are electrically comparable to filters designated level KH,

the highest environmental screening level. This ensures consis-

tency between your prototype or test system using level OO filters

and your flight system using filters with higher levels of environ-

mental screening and radiation tolerance. Element evaluation

(screening at the component level) of Class H or Class K filters

ensures even greater reliability. Refer to Table 1, 2, and 3 for more

information.

• Environmental screening levels to standard (O), Class H (H),

or Class K (K) requirements. See page four for screening

details.

• Technical reports :

Radiation Susceptibility Analysis

Electrical/Thermal Stress Analysis and Derating Report

MTBF Report (Mean Time Between Failures)

FMEA Report (Failure Modes and Effects Analysis)

OPERATING TEMPERATURE

RIPPLE REDUCTION

The filter operates at full load over the temperature range of -55°C

to +125°C case. Above +125°C, the current must be derated as

specified on page two.

The SFMC28-461 EMI filter, when used with Interpoint’s converters,

reduces reflected input ripple current by a minimum of 55 dB at 500

kHz and 60 dB at 1 MHz. The filter and converter combination

performance exceeds the CEO3 requirements of MIL-STD-461C.

PACKAGING FOR SPACE

SFMC28-461 EMI filters are encased in high-reliability, hermetically-

sealed metal packages and weigh just 48 grams. A small footprint of

2.110 Inches (53.59 mm) by 1.115 inches (28.32 mm) by 0.400

inches (10.16 mm) minimizes the board area needed for the filter.

Cover marking inks are NASA approved to Total Mass Loss (TML)

and Collected Volatile Condensable Material (CVCM) outgassing

requirements for operation in space environments.

INSERTION LOSS

The maximum DC insertion loss for the SFMC28-461 filter (at a load

of 22 watts) represents an output power loss of less than 2%.
