Through Hole Resistors | Farnell® UK

We offer a wide range of through hole resistors from many manufacturers, with resistance values from 0.005ohm to 500Gohm, and power ratings from 50mW to 5kW.

What materials are used in through hole resistors?

Resistors can be composed of a variety of materials. Most modern, commonly used through-hole resistors have a wirewound or film construction. A wirewound resistor has a length of resistive wire that is wound around a supporting element from one end to the other. Most film resistors are composed of a carbon, metal, or metal-oxide film. In these resistors, a thin film of conductive material is deposited onto the ceramic element and a helix is cut from one end of the element to the other. It is then covered by an insulating material.

Through hole resistor size

As opposed to SMD resistors , through-hole (THT) resistors are not standardised, and manufacturers may use slightly different measurements. THT resistors are also sized based on their power ratings and their type, e.g. carbon material, wire-wound, carbon film, and metal film. For example, the width of a common 1/2W resistor is 9.2mm, while the length of a smaller 1/4W resistor is 6.3mm. Make sure you check the manufacturer’s datasheet whenever you need to know a component’s exact size.
