Codeco
Codeco, using their “resistor” name of VPR (Vermont Precision Resistor) inventories over nine million resistors to give their customers overnight service if necessary. They specialize in tight tolerance, tight TC parts in almost all of the military standard values. They 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. They have expanded their 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.
Codeco Corporation was established in 1954 for the purpose of designing and manufacturing precision radio frequency attenuators. For a number of years, they 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 their "resistor name" of VPR, formerly Vermont Precision Resistor, inventories over seven million resistors to give customers overnight service in most cases. They stock all military standard values and TCs at 1% through 0.1% They even have a large stock at 10ppm/?C and 5ppm/?C. Codeco also stocks many long term special requirement parts at the request of their customers.
Codeco has an up to date lab for the design and manufacture of artwork for printed circuit boards. They also have a line of energy monitoring and controlling equipment including: demand controllers for residential and commercial use; demand monitors for industrial use, into the magawatt range; power panel controllers for use with electric storage heat.
Codeco also does custom design and assembly on a sub-contract basis and they still manufacture the finest R.F. and I.F. attenuators available.
