varistor

Examples

• All

• MOVs (metal oxide varistors) absorb power throughout the component mass but have a high leakage current, causing measurement errors in instrumentation circuits.

  Academic text (1996)

• When the tube is presented with a transient voltage, it acts like a voltage-dependent switch diverting the transient to ground, not absorbing the energy within the device as do diodes and varistors.
