DESCRIPTION
The Interpoint® STF28-461 Series™ of EMI Filters offers up to 0.8 amps of throughput current. The low profile STF28-461 filters are manufactured in our fully certified and qualified MIL-PRF-38534 Class K production facility and packaged in hermetically sealed steel cases. They are ideal for use in programs requiring high reliability, small size, and high levels of radiation hardness assurance. It has been designed as a companion for the Interpoint SMSA flyback power converters. Multiple SMSA power converters can be operated from a single filter provided the total power line current does not exceed the filter’s maximum rating. The STF28-461 filter will reduce the SMSA’s power line reflected ripple current to within the limit of MIL-STD-461C, Method CE03.
