High Voltage Hi-Meg Resistance Resistors


Tokenchina Hi-Meg High Resistance Resistors are vacuum sealed in a glass envelope and designed for use in electrometer circuits where a high performance is required.

The Hi-Megs resistors achieve a high degree of accuracy and stability, and operate at this high performance level for an extended period of time. RH1 is a hermetic resistor with high resistance characteristics and suitable for ultra-high vacuum applications.

The Hi-Meg RH1 series meets RoHS compliant. Detailed specifications, both mechanical and electrical, please contact our sales representative for more information.

Handling and Cleaning of RH1 Resistors

  • These glass encapsulated (hermetic) resistors with high resistance value is required extraordinary cleanliness.
  • It should be handled by the leads, unless gloves are worn.
  • Fingerprints on the surface of the resistor will attract contaminants and moisture, which will cause a parallel resistance path, reducing the resistance value of the device.
  • If cleaning should become necessary, use isopropyl alcohol and lightly wipe dry with lint free tissues such as Kimwipes.
