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:

  • Voltage Ratings to 50kV
  • Ultra High Stability
  • TCR to 50 ppm/°C
  • Resistance Values to 10 Gigohms
  • Very Low Noise
  • VCR to 0.1 ppm/V
  • Non-Inductive
  • Tolerances to 0.1%
  • Custom Configurations

Electrical Specifications

Electrical Specifications Table

The continuous maximum applied voltage cannot exceed the maximum power rating and is ohmic value dependent.
Value range is case size dependent.
For custom sizes and configurations, consult factory.
