FME28-461

The Interpoint FME28-461 is an EMI input filter module engineered to suppress conducted electromagnetic interference on nominal 28V DC power buses up to 15A of throughput, housed in a rugged M-DIP package. As part of Interpoint’s established FME28 series, it integrates differential and common-mode filtering to attenuate both emissions and susceptibility noise, helping systems meet MIL-STD-461 compliance requirements without disrupting power integrity. The low-profile, through-hole M-DIP form factor simplifies board-level integration in space-constrained embedded power architectures, while the device’s low DC resistance minimizes voltage drop across the filter under full load, preserving overall power converter efficiency.

These filters are commonly deployed in mission-critical electronics across aerospace, defense, and high-reliability industrial sectors, where they condition power inputs for DC-DC converters, avionics power management units, radar systems, satellite bus power distribution, and vetronics platforms. In such environments, consistent input filtering is essential to protect downstream regulators from line-conducted transients and to prevent system-level self-interference. From a procurement standpoint, Interpoint components are associated with extended product lifecycle stability, an important factor for programs requiring decades-long sustainment. Engineers and purchasers should verify suffix variants for screening levels (e.g., standard versus full military processing), as Interpoint often offers multiple reliability grades. Securing these filters through authorized supply channels ensures full traceability and authentic, qualification-backed product for long-term program integrity.
