Tepro was originally incorporated in 1968. It was an acronym for Thom Electronic Products. It quickly built a reputation of high quality power and precision resistors. In 1980, Tepro was acquired by Electro Technik Industries, Inc (ETI). Under ETI management, Tepro expanded from almost exclusively wirewound products into metal film and networks as well.

In 1992 ETI purchased Vamistor Inc. a resistor manufacturer located in Severville, Tennessee. This increased the amount of resistive capabilities available to ETI including carbon film resistors. In the years that followed, the resistor “group” of ETI has evolved into Tepro-Vamistor. Their specialty remains precision and power resistors and quality is still our focus and obsession.
