Expanding the company’s portfolio of metal oxide varistors are components designed for protecting primary and secondary circuits spanning three types. The AVTP types are for primary protection with ...

The ZVE Series is a low-capacitance, surface-mount, multilayer varistor designed for ESD protection. High capacitance can distort or even block communications signals. Because the ZVE Series is a ...

The regulation of power-based products and components is critical for design development and user safety. For decades, the International Electrotechnical Commission (IEC) has dictated how to design ...

KOA Speer Electronics has launched the NV73S series of multilayer metal-oxide varistors, which handles a surge current of up to 6,000 A, claiming five times higher protection than existing products.

Varistor ceramics, predominantly based on SnO₂, are engineered to exhibit a highly non‐ohmic current–voltage relationship that is critical in safeguarding electrical circuits from transient voltage ...
