Technical Specifications

The specific technical specifications for the ZNRV10221U include a varistor voltage of approximately 220V, a maximum surge current rating that varies depending on the waveform and number of surges (consult the datasheet for precise values), and a clamping voltage that determines the level to which the transient voltage is limited. It typically comes in a disc-shaped package with radial leads. The energy absorption capability is another critical parameter to consider when selecting a varistor.

Always refer to the official Panasonic datasheet for detailed electrical characteristics, surge current ratings, derating curves, and safety information before using the ZNRV10221U in any application.
