Multilayer Varistors offer nickel-barrier termination.
Electronic Components & Devices

Multilayer Varistors offer nickel-barrier termination.

Multilayer varistor (MLV) products, with nickel-barrier termination, enhance solderability by improving wetting characteristics of termination to resist sliding and tombstoning during board-assembly process. Plated-nickel layer is placed over standard silver termination to ensure that termination is immune to solder leaching. Tin plating, placed over nickel layer, improves solder wetting...
