Increased power is achieved by a special film process and high
grade alumina cores. The unique structure of these resistive
materials also offers improved stability under overload and surge
conditions.
T erminations are welded for increased durability and negligible
noise levels. Marking is stamped or color banded.
Coating is resistant to most flux removers and cleaning solvents
but should not be brushed while wet. Consult factory for
application assistance.
