Description

Description: Disc construction with radial lead epoxy overcoating Voltage dependent resistors are designed to protect equipment from transient voltage glitches. When a voltage glitch occurs, it connects directly to the power rail, while in standby mode, the baristor quickly changes impedance from normal high impedance to very low levels, absorbing unwanted high voltage to protect voltage-sensitive components.
