About JMK

JMK was established in 1975 to design, manufacture and distribute commercial EMI/RFI powerline filters and associated devices.

Since then, with 45+ years of business operations, JMK has grown to include all forms of EMI and RFI suppression devices; having designed thousands of different filters, suppressors and associated power conditioners for commercial, military, medical and transit applications.

Today JMK maintains two manufacturing facilities and two engineering departments. JMK provides the highest quality of products and is ready to help you meet your power entry filter requirements.

This online catalog provides a cross section of these designs. While this catalog is far from exhaustive, it does provide a reference to our more popular designs.

To best support our customers needs, JMK maintains an in – house test facility with state of the art equipment to test for compliance with FCC, IEC, VDE, Tempest, Mil-Std 461 and Mil F 15733. All of JMK’s products are designed to meet the safety requirements of UL, CSA, VDE and TUV.

Our engineering staff can provide a number of helpful services, including testing your system and selecting or designing a filter to meet your specific needs.
