Product Type: EMI Filters
Application: Space

The SFME28-461 EMI filter modules reduce the reflected input ripple current of high frequency DC-DC converters. One filter can be used with multiple converters up to the rated output current of the filter. The SFME28 filter screening offers 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. SFME28-461 EMI filters are on DLA Drawing 95004
