Advantages

We recognize innovation as an essential element of successful military and space programs.  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.  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. Ohmcraft’s Micropenned serpentine patterned resistors produce superior electrical characteristics:

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

Electrical Specifications

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.
