Dimensions
This range of power wire-wound resistors are wound on continuous glass fiber
elements or have a ceramic core depending on resistance value. The element is
housed in a ceramic case and sealed with an inorganic silica filler.
Their construction gives a resistor with high insulation resistance and low surface tem-
perature, capable of withstanding high overload currents. These resistors are ideally
suited to a variety of applications within industrial and commercial
environments, where performance and reliability are of prime importance.
Applications include fan force ovens, cooker hoods, power supplies and triac based
speed controls. Custom Design Variants in value and style are welcomed.
