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
SM Series Data Sheet

SM Electrical Specs

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.
