Wirewound & Metal Film Resistors

For over 50 years Tepro has been designing and manufacturing both wirewound resistors and metal film resistors for their chassis mount resistor, power resistor, and surface mount resistor lines. Tepro's manufacturing has the ability to make tight tolerance resistors while achieving very high reliability on all their resistors. They offer a complete line of wirewound resistors and metal film resistors including precision wirewound resistors & power resistors in both standard resistor and custom resistor models. Through the Vamistor division they also offer a line of RL42 resistors, these are carbon film type resistors. For convenience, Vamistor carbon film resistors and RL42 resistors can be found here: RL42 resistors, carbon film resistors.

Current Shunt

A Current Shunt resistor may seem to be a simple component, but its function is vital. The component pictured is a Precision, Low Ohm, 4 Terminal Current Shunt and is used wherever current sensing is desirable. Depending on size, this series has a power rating of 1 to 13 watts all with a highly stable electrical configuration.

Surface Mount Resistors

This type of surface mount resistor is available in a metal film or wire wound configuration. The advantage is that it can be mounted directly to the board via pick and place, and has a lower profile than standard thru-hole axial leaded resistors. The power rating on these range from 0.5 watts up to 3 watts. They are also available in non-inductive windings with tolerances to 0.01%.

Carbon Film Resistors

This film resistor is a high voltage metal alloy resistor. As the name implies, the resistors are made by depositing a layer of carbon on the ceramic and then spiraling the surface to achieve a specific resistance. These are available is 3.5 KV (kilovolts) up to 15.0 KV. They are mainly used in high voltage and high temperature applications. For more information please read our article: High Voltage Carbon Film Resistors.

Chassis Mount Resistor

The Chassis Mount Resistor is an aluminum housed power resistor. The heat sink directs the heat away from the resistor allowing for higher wattages than typical free-air type resistors. These are available with power ratings from 5 watts up to 250 watts and resistor tolerances down to 0.01%.
