Cermet ElementsCermet elements are avai lable in a

wide range of resista nce values a nd tapers.They offer e ss entially infinite reso lutionand excellent stability in the most severeenv i ronmenta l condi t ions . S ta t i c anddynamic noise (CRV) performance is goodbu t no t a s good a s tha t o f condu ct iveplastic.

The tem perature c oefficient of c ermetelements , though not as good as wire-wound elements, is better than conductive

plastic or carbon type elements. Linearityis quite good for a film type element andcan be improved considerably for greaterdial setting a cc urac y by las er tailoring.

Frequency response of cermet materialsis very good and the practical applicationrange e xtends w ell beyo nd 100 MHZ.

Conductive Plastic ElementsConductive plastic is a thick film ink,

similar to cermet, but has a smoother sur-fac e. This cha racteris t ic of fers s everalo p e r a t i o n a l a d v a n t a g e s o v e r c e r m e t .Dynamic noise characteristics (CRV oroutput smoothness) and rotational life aremeasurably improved as a result of thesurface smoothness.
