Cermet elements are available in a wide range of resistive values. They offer essentially infinite resolution and excellent stability in most severe environmental conditions. Static and Dynamic noise (CRV) performance is good but does not match that of conductive plastic. The temperature coefficient of cermet elements, though not as low as for wirewound elements, is better than conductive plastic type elements. Frequency response of cermet materials is very good and the practical application range extends well beyond 100MHZ.
