Commercial Grade Power Axial Wirewound Resistor

TT Electronics

The Commercial Grade Power Axial Wirewound Resistor (designated as the CCW Series) provides design engineers with a rugged power wirewound device capable of handling temperatures as high as 275 C.   The ceramic core resistors feature a welded construction, conformal coating making them suitable for a variety of high volume power electronic applications including those in high temperature harsh industrial environments.
