1 FEATURES Excellent anti-surge characteristics Stable characteristics to moisture resistance even in high resistance range. Good replacement for ceramic plate resistors. APPLICATIONS Telecommunication Industrial Medical equipments Laser printer TYPE D 0.8 Dimensions ( mm ) L L 2 Max. d ( 0.05) DESCRIPTION A metal glazed film is deposited on a high grade ceramic body. After a helical groove has been cut in the resistive layer, tinned electrolytic copper wire are welded to the end- caps. The resistors are coated with a red non flammable lacquer witch provides electrical, mechanical and climatic protection.
