ERSE's cement wire wound resistors are constructed for applications requiring minimal board space, low heat dissipation, and low cost. These audio grade resistors are packaged in a nonflammable cement casing and with an inorganic potting mix. This combination provides resistance to the elements and high thermal conductivity. With features like High Surge Capabilities and small sizes, the ERSE cements wire wound resistor is perfect for all high power applications.
ERSE resistors are available in many stocked and un-stocked values. View parts list for more information!
