High Voltage Axial Resistors (HVA Series)

 Printable PDF version of datasheet

Advantages

Our patented Micropen® precision printing technology provides superior precision, thick-film resistors. Ohmcraft’s Micropenned resistors produce superior electrical characteristics including:

  • Ultra High Stability
  • Very Low Noise
  • TCR to 50 ppm/°C
  • Voltage Ratings to 50kV
  • Tolerances to 0.1%
  • VCR to 0.1 ppm/V
  • Non-Inductive
  • Resistance values to 50 GΩs
  • Custom Configurations

Electrical Specifications

The continuous maximum applied voltage cannot exceed the maximum power rating and is resistance value dependent.
For resistance values below 100 KΩs or for custom case sizes, consult factory.
