Vishay RH-NH Series

Vishay High Temp Resistors

High-Temperature Products

Vishay offers high-temperature resistors, capacitors, inductors, and semiconductors. In oil and gas drilling, the instrumentation is exposed to harsh environments, including extreme temperatures, pressure, moisture, shock, and vibration. Once commissioned, the instrumentation must be relied upon to function for 5 to 10 years, and be powered at very high temperatures with no maintenance. The components used for this instrumentation must be able to withstand these harsh conditions while maintaining accuracy. Failure of the data would necessitate its removal for repairs, causing costly delays. Vishay helps to avoid this possibility by offering several high-reliability and high-precision resistors, capacitors, inductors, and semiconductors.
