BCcomponents DATA SHEET AC01/03/04/05/07/10/15/20 Cemented wirewound resistors Product specification 2000 Oct 20 Supersedes data of 17th November 1998 File under BCcomponents, BC08BCcomponents Product specification Cemented wirewound resistors AC01/03/04/05/07/10/15/20 FEATURES DESCRIPTION The resistor is coated with a green silicon cement which is not resistant to High power dissipation in The resistor element is a resistive wire aggressive fluxes. The coating is small volume which is wound in a single layer on a non-flammable, will not drip even at ceramic rod. Metal caps are pressed High pulse load handling high overloads and is resistant to most over the ends of the rod. capabilities. commonly used cleaning solvents, in The ends of the resistance wire and the accordance with MIL-STD-202E, leads are connected to the caps by method 215 and IEC 60068-2-45. APPLICATIONS welding. Tinned copper-clad iron leads with poor heat conductivity are Ballast switching employed permitting the use of Shunt in small electric motors relatively short leads to obtain stable Power supplies. mounting without overheating the solder joint.
