Varistors, MOVs are in stock at Tenco Electronics.A varistor is an electronic component with an electrical resistance that varies with the applied voltage.[2] Also known as a voltage-dependent resistor (VDR), it has a nonlinear, non-ohmic current-voltage characteristic that is similar to that of a diode. In contrast to a diode however, it has the same characteristic for both directions of traversing current. At low voltage it has a high electrical resistance which decreases as the voltage is raised.Tenco offers inventory, pricing, & datasheets for Varistors, MOVs .
