Product Type: EMI Filters
Application: Space

The SFMC28-461 EMI space filter modules reduce the reflected input ripple current of high frequency space systems Interpoint® DC-DC converters. One filter can be used with multiple converters up to the rated output current of the filter. SFMC28-461 are available certified to Space Prototype (O), Class H, or Class K with radiation hardness assurance (RHA) levels of “-” (O, no rating) or H 1000 krad(Si) per MIL-PRF-38534. SFMC28-461 EMI filters are on DLA Drawing 94010.
