Vishay VR68 Series High Voltage Metal Glaze Resistor, 10MΩ, 1W, ±5%, 10kV

The Vishay VR68 Series High Voltage Metal Glaze Resistor is engineered for demanding electronic applications requiring exceptional stability under high voltage conditions. Constructed from a high-grade ceramic body with a precision metal glazed film deposition, this resistor delivers outstanding reliability. A helical groove is cut into the resistive layer to achieve the precise resistance value, and tinned electrolytic copper wires are welded to the robust end-caps for secure connectivity. The component is finished with a distinctive light blue protective lacquer, offering excellent electrical insulation and robust mechanical and climatic protection.

This leaded resistor is designed for environments where high resistance, high stability, and high reliability at elevated voltages are critical. Its performance makes it ideal for use in challenging settings such as high-humidity conditions, within white goods appliances, and in various power supply units. The series meets rigorous international safety standards including IEC 60065, EN 60065, VDE 0860, and CQC (China), ensuring compliance for global markets. With a high pulse loading capability of up to 10kV, it is built to withstand transient surges.
