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 aluminium
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.
