EMI Filter Company

EMI Filter Company, a division of Nordquist Dielectrics, manufactures bulkhead mounted low pass filters in threaded, solder-in, and press-in styles to the microwave communications industry. All EMI filters are made in the U.S.A. Our patented process allows us to match stocked capacitors with stocked filter body assemblies to provide the best lead times in the industry. At EMI, since our focus is solely on filters, we are not only able to provide you with standard filter sizes, we are also able to build custom filters to your specifications. All our filters are 100% tested to ensure their quality. Our parent company, Nordquist Dielectrics, was founded in 1972 for manufacturing and selling ceramic multilayer discoidal capacitors to filter manufacturers.
