    Carbon film resistors are the workhorses of the resistor world, offering a sound component choice for high-voltage and/or high temperature applications. Since 1958, Tepro of Florida, a subsidiary of Electro Technik Industries (ETI), has manufactured precision and power resistors. Through their Vamistor division, Tepro manufactures various film resistors, including the Tenn-R product line and RL42 carbon film resistor.

    For years, Koehlke has offered Tepro power and precision resistors for commercial and military applications. Many of Tepro’s various metal film resistors are wirewound configuration and have the ability to meet very tight tolerances. Tepro manufactures traditional conformal coated and chassis mount wirewound resistors, as well as metal film resistors, carbon film, thin and thick film networks, and current shunt resistors. Through the Koehlke partnership, custom resistors – both power and precision – can be designed to meet your demanding requirements, and often within the same timeframe as a standard product.


    • Tight Tolerances, including resistors less than 0.5% in tolerance.

    • Product Diversity, including power resistors, precision resistors, metal film resistors, carbon film resistors, chassis mount resistors, zero ohm jumpers, surface mount resistors, wirewound resistors, line feed protectors, current shunt resistors chip resistors, resistor networks, high voltage resistors and thick film resistors.

    • Koehlke is your access to commercial, precision, and established reliability metal film resistors, and metal oxide, carbon film, wirewound and high voltage resistive products.
