How our Military EMI Filters Work
Unlike standard filters for businesses, industries, or scientific laboratories that have a frequency range of 100 kHz to 10 GHz, our military-grade filters are powerful pieces of technology that have broader frequency ranges for RFI interference elimination.
They are strenuously tested in order to make sure that they are compliant with the military’s strict code guidelines, which can be dramatically different from the FCC and CE regulations. They can cover a completely different set of malicious frequencies, and are some of the most powerful electronic components that Tri-Mag, LLC currently offers.
In addition, Tri-Mag, LLC builds a wide variety of RFI filters and other custom designed electrical components for other prominent industries. Some of our biggest industries served include telecommunications, the medical field, aerospace, and more!
