The WH series from Welwyn are 50W axial leaded wirewound resistors with solder-dipped copper clad steel terminations. Cap and lead assemblies are fitted to a high purity ceramic substrate. The resistive element is wound onto the substrate and welded to the caps. The wound rod is then moulded and fitted into aluminium housing to give optimum stability and reliability. The resistor is legend marked with type reference, resistance value and tolerance which will withstand all accepted industrial cleaning fluids and values are marked in accordance with IEC 62. The aluminium housed wirewound resistor is suitable for severe environments and excellent thermal conductivity to heatsink. Typically used at high power applications.
