EMI/RFI Filters

Enerdoor is an international leader in the design and manufacturing of standard and custom EMI/RFI filters. Electromagnetic interference (EMI), also called radiofrequency interference (RFI), is a high frequency disturbance which affects an electrical circuit due to electromagnetic induction or electromagnetic radiation emitted from an external source.

An EMI/RFI filter is an electronic passive device used to suppress conducted interference present on a signal or power line and to protect a device from electromagnetic interference signals present in the environment. Most EMI/RFI filters consist of components that suppress differential and common mode interference.
