Noise Filters for mobile applications in specialty vehicles, emergency vehicles, and industrial applications, 12V DC, 10 Amps to 150 amps power rating image by Newmar Powering the Network

Noise Filters

The interference or electronic “noise” generated by alternators, ignition systems, motors, etc., can render a vehicle’s radio, data receivers or other electronic equipment virtually useless. This interference takes the form of popping or static on radios or audio gear and garbled images or “hash” on video displays.

These specialized filters can be used singly or in combination to attenuate conducted line noise, either at the affected equipment or at the noise source. The “PC” models feature inductor and capacitor circuit that filters both the “+” and “–” leads. The “IF” model utilizes an inductor and filters the “+” lead only.

Filter Features

  • Heavy duty aluminum construction
  • Operate on 6-48 VDC systems
  • Integral mounting flanges for secure installation, except model IF-16 which is secured in place by tie-wrap
  • Nickel-plated brass stud connectors on alternator filters accommodate high current cables and terminals
  • Color coded wire leads on all other models make in-line installation easy
