High Precision Resistors
TYPE KC SERIES
The KC Series draws together high power and high precision
in one attractively priced silicone coated package.
Windings are accurately space wound on ceramic or alumium
oxide cores. Winding pitch is controlled for high winding
density to obtain maximum power dissipation by transmitting
more heat down the length of the core, thereby lowering
the "Hot Spot" temperature. The resistance wire is welded
to the end cap using the most advanced electronically controlled
D.C.Welders. Where high reliability is required the resistance
wire is sandwiched between a weld tab and the end cap to
provide the ultimate in reliability. Coated power resistors have
high resistance to commonly used solvents.
