About Ohmcraft

Who We Are

Established in 1982, Ohmcraft is the leader in high-performance resistor design and manufacturing. Our expertise in high-voltage resistors (over 40KV) and high-value resistors (over 4 tera-ohms) enables designers to meet and exceed even the most challenging product specifications. Our proprietary Micropen® technology produces superior technical performance in surface-mount, leaded, and network resistors. These resistors also provide industry-leading performance in precision, TCR and TCR tracking, VCR and VCR tracking, low noise, stability, and pulse-withstanding capability.

Micropenning enables us to create this distinctive, serpentine pattern that gives our surface-mount resistors the ability to reach 1T ohm resistance and 3.5KV in operating voltage.

Our Technology

Ohmcraft utilizes its proprietary Micropen technology to pattern thick film materials—including conductive, resistive, and dielectric inks. Micropenning applies a continuous, fine-line serpentine pattern to the surface material, resulting in precise thickness and ohmic value with the industry’s highest stability.
