Ultra High Voltage Chip Resistors (UHVC Series)
Advantages
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
Note 1: For these values and package size, refer to our standard HVC series. Due to the high voltage ratings, these resistors must be potted upon assembly. or other configurations or requirements, contact ohmcraftsales@exxelia.com.
