Vishay VR Series Anti-Surge Resistors are UL-approved and meet safety requirements including IEC 62368-1 and CQC. The VR anti-surge resistors feature a metal-glazed film deposited on a high-grade ceramic body, with tinned electrolytic copper wires welded to the end caps. These resistors offer high pulse loading capability with a maximum of 10kV and support a resistance range from 100kΩ to 68MΩ. VR anti-surge resistors operate at a temperature range from -55°C to +155°C and exhibit a maximum resistance change of 1.5% after 1000 hours at rated dissipation. Typical applications include automotive electronics, high-humidity environments, power supplies, and white goods.
