20 Watt

ERSE’s resistors are constructed for applications requiring minimal board space, low head dissipation, and low cost. These audiophile 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.
