Absorber materials are used for EMI isolation and RF absorption. They are available in different materials to provide absorption from as low as 5 MHz up to 110 GHz.

Comprising materials such as loaded urethane, silicone, nitrile, neoprene thermal plastic and foam, there are many choices available to provide products that can be characterised to provide absorption at single or multiple frequencies. We also offer absorber heat shrink tubing and extruded cable absorber (to eliminate ferrite chokes).
