Z – LEAD SURFACE MOUNT SPECIFICATION AC AXIAL CEMENTED WIREWOUND RESISTOR & PR POWER METAL FILM RESISTORS FEATURES · Surface mounted version · Low cost alternative for SMD molded resistor · High power dissipation in small volume · High pulse load handling capabilities · High temperature silicone coating TECHNOLOGY Wire wound resistor AC03 / AC05 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 tinned copper-clad leads are connected to the caps by welding. The resistor is coated with green silicon cement which is non-flammable, will not drip even at high overloads and is resistant to most commonly used cleaning solvents, in accordance with “MIL-STD-202E, method 215” and “IEC 60068-2-45”. Metal film power resistor PR03 A homogenous film of metal alloy is deposited on a high-grade ceramic core. The leads are welded on this caps and a helical groove has been cut in the resistive layer. The resistor is coated with red silicon cement which is non-flammable, will not drip even at high overloads and is resistant to most commonly used cleaning solvents, providing electrical, mechanical and climatic protection.

     MARKING WIRE WOUND RESISTOR The resistor is marked with the nominal resistance value, the tolerance on the resistance and the rated dissipation at T = 25 ºC. amb For values up to 910 W, the R is used as the decimal point. For values of 1 KW and upwards, the letter K is used as the decimal point for the KW indication. Example: 6K8 5% 5W FILM RESISTOR The nominal resistance and tolerance are marked on the resistor using four or five colored bands in accordance with IEC publication 60062 “color code for fixed resistors”. Standard values of nominal resistance are taken from the E24/E96 series for resistors with a tolerance of ±5% or 1%. The values of the E24/E96 series are in accordance with “IEC publication 60063”.
