Voltage-dependent resistor |
摘要 |
A voltage-dependent resistor or varistor is composed of a monolithic ceramic body made up of a plurality of layers of varistor material containing zinc oxide, alternating with layers of precious metal serving as coatings on the layers and which are alternatingly electrically connected to separate locations on the exterior surfaces of the body. The porosity of the layers of varistor material does not exceed 5%; the proportion of bismuth is at most 1 mol %; and the precious metal coatings include 50-80% by weight of palladium.
