Model Number
Varistor
Specifications: Varistors are voltage-dependent, nonlinear device, which have an electrical behavior similar to back-to-back zener diodes. Zinc-oxide varistor are nonlinear resistor, consisting main of zinc oxide and several kinds of metal oxide additive. The varistor\'\'s stand-by state has a high impedance in relation to the component to be protected and does not affect the characteristics of the electric circuit. In the presence of transient voltage, the varistor then has a low impedance and short circuits, I. E. The assembly device to be protected. Application: Surge protection in consumer electronics Sizes:5.0mm,7.0mm,10.0mm,14.0mm,18.0mm,20.0mm Material: Mainly zinc oxide Varistor voltage range from 18v to 1100v Maximum current range from 100a to 15000a Maximum energy range from 0.4 joul to 480 joul Typical response time: Less than 25ns Insulation resistance: More than 1000mohms Approval: Ul1414, ul1449 (2nd edition), csa, vde We are providing: 1) any colors and sizes 2) special quantity packing 3) quality green product (rohs) 4) samples 5) small orders accepted 6) good service 7) better price Please contact us for more detail
