About

Your equipment most likely already has some kind of EMI filter, perhaps several. If they were that effective, why then did you end up looking for more filters?  What works for CE/FCC EMC compliance does not necessarily work where it matters - where equipment is used. OnFILTER's patented EMI filters work where ordinary filters amplify EMI instead of suppressing it.  OnFILTER designs and manufactures EMI filters for many applications: industrial, motion control, ESD/EOS protection, medical, R&D, data centers and many others.  Filter lines include AC and DC power, ground, soldering, PWM-based drives (servo and VFD), data and others.
OnFILTER is based in Santa Cruz, CA.  All OnFILTER' products are manufactured in the U.S. and are sold worldwide.
