Vishay / Dale EMIF-1S1P-481N EMI Filter Reference Design

Vishay / Dale EMIF-1S1P-481N EMI Filter Reference Design provides a rapid prototyping solution for single-phase, single-stage EMI filters, using the 480nH ICMS2321 common mode choke. The EMIF-1S1P-481N board includes a set of THT X and Y capacitors placed around the common mode choke, creating a full filter that can be tested out of the box. The versatile PCB allows users to test filter designs based on Vishay's ICMS2321ABEH481N10 common-mode chokes, film, and ceramic capacitors. Users can test a prebuild and alter the components based on application needs. The footprints are designed to support multiple capacitor options.

Features

  • Versatile PCB tests various filter designs based on Vishay's ICMS2321ABEH481N10 common-mode chokes, film, and ceramic capacitors
  • Prebuild design can be tested and the components easily altered to customize according to needs and application
  • Footprints are chosen in such a way that a wide variety of capacitors can be used
