Military Grade High Voltage Chip Resistors (MCH Series)

Advantages

We recognize innovation as an essential element of successful military and space programs. Exxelia Ohmcraft has served markets in electronic warfare, weapons platforms, force protection, intelligence and space programs for over two decades, reliably supporting a wide range of products, programs, and applications. Our custom resistors are designed to support the rigorous specifications required by military and space suppliers who depend on the precision and reliability of our products. Exxelia Ohmcraft is able to screen and qualify our resistors to the following specifications: MIL-PRF-55342, MIL-PRF-49462, NASA EEE-INST-002 (Level 1 & 2).

Our patented Micropen® precision printing technology provides ultra precision, thick-film high voltage, military grade, surface mount resistors. Our military SMT chips have extended TCR temperature range and are stringently inspected. Exxelia Ohmcraft’s Micropenned serpentine patterned resistors produce superior electrical characteristics:

  • Voltage Ratings to 5000 Volts
  • Resistance Values to 50 Gigohms
  • Extended TCR Range
  • Ultra High Stability
  • Very Low Noise
  • Tolerances to 0.1%
  • TCR to 25 ppm/°C
  • VCR to 1 ppm/V
  • Custom Configurations
