Code: CP76H

Product details

Transient Suppressor Metal-Oxide Varistor

These devices are simply connected directly across the power supply. They have a very high resistance up to the Vm voltage shown in the table below and therefore usually may be ignored, but the moment a transient spike appears on the supply line which exceeds Vm, the impedance of the device drops immediately to a very low level while it dissipates the unwanted energy. For example, Suppressor 275Vac can be connected directly across the UK mains supply.Please note that the use of AC in the description is simply an indication of its most likely use. Both types can be used equally in AC or DC circuits up to the Vm stated.* Current ratings are for a typical transient pulse where peak current is reached in 8µs and the pulse has decayed to 50% of its peak value after a further 12µs. It is a standard method of rating these devices and is usually described as an 8/20µs current wave rating.
