AC01/03/04/05/07/10/15/20 Cemented wirewound resistors Product specification Supersedes data of 17th November 1998 File under BCponents, BC08 2000 Oct 20 BCponents Product specification Cemented wirewound resistors AC01/03/04/05/07/10/15/20 Features DESCRIPTION The resistor element is a resistive wire which is wound in a single layer on a ceramic rod. Metal caps are pressed over the ends of the rod. The ends of the resistance wire and the leads are connected to the caps by welding. Tinned copper-clad iron leads with poor heat conductivity are employed permitting the use of relatively short leads to obtain stable mounting without overheating the solder joint. The resistor is coated with a green silicon cement which is not resistant to aggressive fluxes. The coating is non-flammable, will not drip even at high overloads and is resistant to most monly used cleaning solvents, in accordance with “MIL-STD-202E, method 215” and “IEC 60068-2-45”. - High power dissipation in small volume - High pulse load handling capabilities. APPLICATIONS - Ballast switching - Shunt in small electric motors - Power supplies. ..
