Vishay VR68 Series 1MΩ 1W 10kV High Voltage Metal Glazed Resistor

Vishay VR68 Series 1MΩ 1W 10kV High Voltage Metal Glazed Resistor is a through-hole, axial leaded resistor rated at 1MΩ, 1W and 10kV. It is designed for high-voltage applications where reliable performance under high voltage and pulse conditions is required.

Overview

The Vishay VR68 Series uses a metal glazed film deposited on a high-grade ceramic body. A helical groove is cut into the resistive layer, often using a specialised laser, to achieve the target resistance value without damaging the ceramic substrate. Tinned electrolytic copper wires are welded to the end-caps, and plated-steel termination caps are pressed onto the metalised rods for secure connections.

Key Features

• High pulse loading capability, with a maximum of 10kV
