Description
The OV Series varistor/suppressor is a dual function device that protects against
transient voltages and radio-frequency noise generated within 12VDC and 24 VDC
vehicle power systems. This component replaces two components: a low voltage
varistor and a capacitor.
The OV Series incorporates a varistor function in automotive applications and a radio-frequency filter operating in the
capacitance range from 0.47μF to 1.5μF. These components are designed for protection of all sensitive electronics
circuits from both voltage transients and high-frequency noise produced by electromechanical devices such as relays,
electric motors, etc.
OV varistors/suppressors are square-shaped components with in-line leads, which require at least 30% less mounting
space than the two components they re place.
