BCcomponents DATA SHEET PR01/02/03 Professional power metal film resistors Product specification 2001 Jul 13 Supersedes data of 8th March 2001 File under BCcomponents, BC08BCcomponents Product specification Professional power metal film resistors PR01/02/03 FEATURES DESCRIPTION climatic protection. This coating is not resistant to aggressive fluxes. The High power in small packages A homogeneous film of metal alloy is encapsulation is resistant to all deposited on a high grade ceramic Different lead materials for different cleaning solvents in accordance with body. After a helical groove has been applications MIL-STD-202E, method 215, and cut in the resistive layer, tinned IEC 60068-2-45. Defined interruption behaviour. connecting wires of electrolytic copper or copper-clad iron are welded to the end-caps. The resistors are coated with APPLICATIONS a red, nonflammable lacquer which All general purpose power provides electrical, mechanical and applications.
