Varistors boost surge capability to 13kA
VISHAY INTERTECHNOLOGY BCcomponents VDRUS series of VDR metal oxide varistors (MOV) are certified for operation up to +125°C in accordance with UL 1449 edition 4, VDE/IEC 61051-1/2. Designed to provide overvoltage and transient voltage protection in consumer goods and industrial applications, devices provide 30% higher surge current capability than previous-generation devices. Offered in standard 7mm, 10mm, 14mm and 20mm sizes, devices consist of a high purity zinc oxide disc with two solid copper leads or copper-clad steel wires with matte tin plating. Products deliver high temperature performance as a result of its UL94-V0-approved, flame-resistant silicone lacquer coating, which provides electrical, mechanical, and climate protection. Devices come with current surge capability from 1.8kA to 13kA, rated voltages from 115 Vac to 680Vac, energy absorption from 19J to 720J, and straight or kinked leads.
