Suntan : Varistor from Suntan

Posted February 17,2012 * Comments(0)

A varistor is a type of resistor with a significantly non-ohmic current-voltage characteristic. Which have symmetrial voltage-current characteristics and unparalleled large peak current capability are used for absorption of  transient voltage, suppression of pulse noise and circuit voltage stabilization.

The most common type of varistor is the Metal Oxide Varistor (MOV). This contains a ceramic mass of zinc oxide grains, in a matrix of other metal oxides (such as small amounts of bismuth, cobalt, manganese) sandwiched between two metal plates (the electrodes). The boundary between each grain and its neighbour forms a diode junction, which allows current to flow in only one direction. The mass of randomly oriented grains is electrically equivalent to a network of back-to-back diode pairs, each pair in parallel with many other pairs.

Suntan's MOV is exactly TSV series, including different diameters like 05D, 07D, 10D, 14D and 20D. Common packing is Bulk, Ammo and Tape&Reel Packing are also available upon special request.
