Varistors Guard Against Static And Surges

Designed to protect components against static electricity, switching and incoming surges, the NV73 series metal-oxide varistors feature a large withstanding surge capability and symmetrical V-l characteristics. This makes surge absorption possible in either direction. The varistors are available in 0603, 0805 and 1206 sizes. Voltages range from 4.2V to 56V with maximum peak current at 8 µs and 20 µs of 30A, 10A to 50A, and 30A to 70A depending on the size and style selected. Their chip-type design makes them safe for assembly with surface-mount placement automated assembly machines. The components are available in plastic tape and reel packaging.
