The Laird Noise Suppressor line features a high impact molded plastic housing with components encapsulated in a waterproof, vibration proof compound. Heavy gauge wire and a high current
rating make them ideal for the two- way radio, cellular, marine, C.B., or car audio dealer.
This quality product is a general purpose low pass filter, used to reduce power line noise in both Audio Frequency and RF ranges. Noise is commonly generated by the alternator, ignition system, voltage regulator, and other accessories in the vehicle. Alternator whine is one of the most common problems. It can be identified as a varying pitch corresponding to engine speed that can find its way to either the receiving or transmitting end of the radio. Accessories such as AC fans and electronic fuel pumps may generate RF interference that can be significantly reduced with the Laird Noise Suppressor.
This product can be used in heavy equipment and marine 24 Volt systems to protect sensitive devices from large transient spikes which are commonly generated by the ignition system. Convenient mounting holes are located on the box for easy installation in the vehicle.
