What Caddock Electronics does

Caddock Electronics, Inc. is a privately held specialty manufacturer of high-performance precision resistors and resistor networks, founded in 1962 and headquartered in Roseburg, Oregon. The company designs and manufactures over 250 product models spanning high voltage resistors (up to 48KV), current sense resistors, chip/SMT resistors, high frequency and RF resistors, load resistors, pulse resistors, non-inductive power resistors, and precision voltage divider networks. Its core technology rests on two proprietary resistance film systems—Micronox® (developed in 1962) and Tetrinox®—with specifications including temperature coefficients as low as 2 ppm/°C, tolerances to 0.01%, ultra-stable selected resistor sets to 500 Meg, and patent-pending ultra-fast fault current fusing (sub-20µsec) capability. The product portfolio is differentiated in extreme performance envelopes serving analog precision, high-voltage, and high-reliability applications.

The company serves three primary customer segments: industrial/commercial electronics, military/defense (with 40+ years of specification control drawing support), and space/satellite applications (handled directly by Caddock). Go-to-market combines direct sales for the USA, Canada, and Mexico, full-line authorized distributors across 35+ countries (including AMS Technologies, Milano Brothers, Mettel Electronics, and Rhopoint Components), and catalog distributors (Digi-Key, Mouser, RS Components, Newark, Bürklin, Distrelec) for smaller-volume purchases. Pricing is quote-based for custom and high-reliability solutions with no public pricing disclosed. Caddock holds registered trademarks for Micronox®, Tetrinox®, and Kool-Pack® packaging, has patents pending on ultra-fast fault current fusing technology, and maintains environmental compliance (RoHS, REACH, California Proposition 65, TSCA).

The business operates as a single-site manufacturer in Roseburg with Applications Engineering, Direct Sales, and Export Sales co-located at the headquarters. Caddock is privately held with no disclosed parent company, venture capital investment, or institutional ownership, and no public revenue figures. Recent product activity includes the Type VMN Voltage Monitoring Networks, Type USFS and USGS high-voltage ultra-stable low-TC selected resistor sets, and the MPM20 'Pure Tin Free' TO-220 power film resistor, indicating continued R&D investment in precision analog and power electronics applications.
