Codeco Corporation was established in 1954 for the purpose of designing and manufacturing precision radio frequency attenuators. For a number of years, we built the majority of the laboratory testing standards of attenuation for the Bell system, Western Electric, and Raytheon, to name a few.
In 1969 the company moved to Vermont to take advantage of the work force and the lifestyle that the state had to offer. One recurring problem Codeco encountered was the lack of availability of quality, precision metal film resistors (the heart of all attenuators) with reasonable delivery times. After fighting this problem for over twenty years, Codeco decided to get in to the resistor business - initially as a manufacturer and currently as a supplier.
Codeco, using our “resistor” name of VPR (Vermont Precision Resistor) inventories over nine million resistors to give our customers overnight service if necessary. We specialize in tight tolerance, tight TC parts in almost all of the military standard values. We do stock parts down to a tolerance of 0.01% and temperature coefficients of ±5PPM/°C. We also keep an emergency stock on most repeat orders.
Today, Codeco has diversified into other resistive fields as well. We have expanded our through hole metal film resistor line into a full spectrum of precision surface mount resistors and wirewound resistors, both general purpose and those with extremely tight tolerances and TCs.
