EMI-RFI Filters

EMC Filters For Every Industry and Application

Electromagnetic interference (EMI), or radio frequency interference (RFI), is a type of electric or electronic emission that can degrade, impair or prevent electrical circuit performance.

EMI-RFI filters are used to reduce electromagnetic interference generated by variable frequency drives and servo drives which when installed inside automated machinery create RF disturbances at high frequencies that affect other electrical devices such as nearby machinery, PLCs, sensors or PCs.  Most EMI-RFI filters consist of components that suppress differential and common mode interference.

Within industrial settings machines operate close to each other making them vulnerable to interference and reliant on EMI-RFI filters to prevent RF noise interruptions. This is especially important as interference may cause controls to malfunction, causing faulty outputs, accidents, or production loss due to machine failure.
