Power film resistors

Description

Thanks to their space-saving design, Metallux power resistors with thick-film technology permit a high power density in a confined space.

Features such as low inductance and the ability to deliver high resistance values open up new prospects in power electronics.

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.
