The VP4032K122R150 from KEMET Corporation is a Plastic Encapsulated Varistor that has been designed to protect electronic equipment against high voltage surges occurring in the low and medium voltage region. It has an AC voltage rating of 150 V, a DC voltage rating of 200 V, and a clamping voltage of 395 V. This varistor offers direct surface-mount equivalents to leaded disc varistors of 5 and 7 mm sizes. It is encapsulated with a thermoplastic material that offers non-flammability according to UL 94 V–0 flame-retardant standard, thereby ensuring the safety of operation.

This RoHS-compliant varistor is available in a surface mount package that measures 10 x 8 x 2.3 mm and is ideal for medical instruments, integrated circuits, and transistors, mobile communication, white goods, entertainment electronics, lighting ballasts, as well as the protection of low and medium voltage boards, remote controls, and electrical counter applications.
