TE Connectivity has offered the 'C' Series of Vitreous Enamelled Wirewound Resistors for
more than 25 years and as a result of continuous development and investment in the
latest production equipment now supplies a product with a proven record of reliability and
quality. These economically priced resistors are capable of dissipating high power from a
relatively small size in harsh environmental conditions. The resistors are manufactured
from quality materials for optimum reliability and stability.
