Power wire resistors

Description

Wire resistors combine the high pulse stability of common resistor materials with optimised thermal conduction and a high degree of protection.

Mounting on a thermally conductive surface further improves heat dissipation and increases stability.

We offer wire resistors in various housing designs and materials such as aluminium and steel. They satisfy the requirements of UL508 and are particularly efficient when used as a braking, charge, discharge or heating resistor.

Our portfolio ranges from standard products to products that have been adapted according to your exact requirements.

Tell us your desired output, dimensions and resistance value and we will produce the right resistor element to suit your requirements.
We produce individual samples all the way through to large series containing hundreds of thousands of items.
