High Resistance Chip Resistors (SM Series)
Advantages
Our patented Micropen® precision printing technology provides ultra precision, thick-film high ohmic value, surface mount resistors. Exxelia Ohmcraft’s Micropenned serpentine patterned resistors produce superior electrical characteristics:
- Voltage Ratings to 600 Volts
- Resistance Values to 50 Gigohms
- Ultra High Stability
- Very Low Noise
- Tolerances to 0.1%
- TCR to 25 ppm/°C
- VCR to 1 ppm/V
- Custom Configurations
The continuous maximum applied voltage cannot exceed the maximum power rating and is ohmic value dependent. Value range is case size dependent.
Standard case sizes: 0402, 0403, 0502, 0504, 0603, 0805, 1004, 1005, 1206, 1210, 1505, 2010, 2208, 2510, 2512, 3512, 4020, 5020.
