High Power Resistor Type SBC (Square Ceramic) Series Key Features Up to 17 Watts Fusible Styles Vertical or Axial Non Flammable Special Solvent Resistance Customer Specials Invited Widely Available from Distribution This range of Power Wirewound Resistors are wound on continuous glass fibre 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 temperature, 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.
