The RNP is a resistance with strip wrapped edgeways on ceramic U-bolts mounted on a metal rod. Thanks to this construction the thermal resistance is very low: the strip is in fact free to exchange heat with the surrounding air very effectively. Even in terms of the heat capacity the RNP ensures very high performances. The RNP series does not provide default ohmic values or predetermined resistive alloys. Only the length of the bar is fixed.
