EMI Filters, EMI Suppressions, Ferrite cores, Clip-on Ferrite Ring Core

EMI filter (electromagnetic interference filter) also known as RFI filter, is an electronic passive device which is used in order to suppress conducted interference that is present on a signal or power line. Electromagnetic Interference (EMI) is unacceptable electromagnetic emissions, natural or man-made, which result in the degradation or malfunction of electronic equipment. EMI filters can be used to suppress interference that is generated by the device. Most EMI filters consist of components that suppress differential and common mode interference.

Types of EMI Filters


Coilmaster Electronics produces different kinds of EMI filters. Customer could find the EMI filter on our website categorized by dimension, IDC, impedance, DCR…etc. For instance, our C2L, C4S, RH, SH, SMB series are most common type of EMI Filter in our produce line. Also have clip-on ferrite ring core, noise suppressor cable clip for various diameter cable, from 5mm/7mm/9mm to 13mm.

EMI Filters from Coilmaster Electronics


As mention above Coilmaster Electronics provide full range of EMI filter normally be used to design an RFI filter, EMI filter, Ethernet EMI filter, EMI air filter, EMI line filter, EMI suppression filter, EMI power filter, EMI noise filter, DC EMI filter, AC EMI filter or other circuit which may require an EMI filter. Customer could contact Coilmaster sales person to find the most suitable EMI filter which match your specific EMI filter application need. 

Coilmaster also could provide 100% alternative EMI filter against to other EMI filter manufacturer but with more competitive price and better lead time.
