The 70 amp DC filter is engineered to remove low to high frequency EMI-RFI noise interference that is commonly generated from general aviation, rotorcraft, and military vehicle DC electrical systems. This ultra compact device features universal mounting flanges allowing it to be mounting either vertically or horizontally in installations on a bulkhead or firewall, or in the electronics compartment on any aircraft make and model. This EMI-RFI filter will attenuate noise interference, spikes and surges from the aircraft's avionic buss allowing critical flight electronics to operate with integrity.
