For over 50 years Tepro has been designing and manufacturing highly reliable tight tolerance resistors.
Resistor Capabilities:
Tepro offers a complete line of wirewound resistors and metal film resistors, including precision resistors and power resistors in both standard and custom product. They manufacture precision and power resistors for military and commercial applications. Many of their precision and power resistors are manufactured with the wirewound resistor configuration providing them the ability to meet very tight tolerances and even tighter lead times. Wirewound resistors, however, are not the only type of resistor Tepro manufactures. They also make various metal film resistors and through their Vamistor division, they offer the RL42 line of carbon film resistors.
History of Tepro Resistors:
Originally incorporated in 1959 to produce high-quality wirewound power resistors and precision resistors. Tepro quickly built a reputation for producing these resistors with a specializing in the very tight tolerance resistors. In 1980, Tepro was acquired by Electro Technik Industries, Inc. (ETI), not only because of their reputation for quality but because of their ability to make resistors below 0.5% intolerance. Under ETI management, Tepro expanded from almost exclusively wirewound resistors into metal film resistors and network resistors as well.
In 1992 ETI purchased Vamistor Inc., a resistor manufacturer located in Severville, Tennessee. This increased the number of resistor capabilities available to ETI as a whole but more specifically Tepro. One of the new capabilities available was to manufacture carbon film resistors and military qualified RL42 resistors. In the years that followed, the company/group has evolved into Tepro-Vamistor. Their specialty remains wirewound precision resistors and wirewound power resistors, but as always, quality is their focus and obsession.
