Vishay Intertechnology released a new series of VDR metal oxide varistors (MOV) certified for operation up to +125 °C in accordance with UL 1449 edition 4, VDE/IEC 61051-1/2. The Vishay BCcomponents VDRUS series offers 30 % higher surge current capability than previous-generation devices and it is designed to provide overvoltage and transient voltage protection in consumer goods and industrial applications.
The new devices consist of a high purity zinc oxide disc with two solid copper leads or copper-clad steel wires with matte tin plating. The devices are UL94-V0-approved, flame-resistant silicone lacquer coating, which provides electrical, mechanical, and climate protection, as a result the varistors deliver high temperature performance. The varistors designed to work in power controllers and input filters for appliances such as stoves and washing machines and industrial applications including motor controllers, AC/DC converters, and circuit breakers.
