Varistors

Littelfuse Varistors are protective devices that offer several important features, such as overvoltage protection, peak current ratings from 20A to 70,000A, and peak energy ratings from 0.01J to 10,000J. The mounting options serve a wide range of applications. Littelfuse Varistors also offer many form factor and protection ranges, rugged cost-effective protection, thermal protection options, and RoHS compliance.
