Introduction

The PV series of low and medium voltage plastic-encapsulated varistors is designed to protect electronic equipment against voltage surges in the low and medium voltage region. They offer direct SMD equivalents to leaded disc varistors of 5 and 7 mm sizes. The thermoplastic encapsulation is non-flammable and UL 94 V-0 rated. Contacts are made of tinned copper sheet. PV series varistors are designed for surface mounting and are available in two model sizes. These transient voltage suppressors cover an operating voltage Vrms from 11 V to 300 V, featuring maximum surge currents from 100 A to 1200 A.
