Ultra High Voltage Chip Resistors (UHVC Series)


Our patented Micropen® precision printing technology provides a superior surface mount resistor with the highest voltage ratings available in the industry.

  • Highest voltage ratings available in a surface mount resistor (up to 20,000 Volts).
  • Replace leaded thru-hole resistors with surface mount resistors saving assembly and board space costs.
  • Replace multiple resistor arrays with a single resistor.

UHVC: Setting the Industry Standard

Our Exxelia Ohmcraft serpentine patterned resistors produce superior electrical characteristics, including:

  • Voltage Ratings to 20kV
  • Resistance Values to 50 Gigohms
  • Ultra High Stability
  • Very Low Noise
  • Tolerances to 1.0%
  • TCR to 100 ppm/°C
