TE Connectivity has offered the C Series of vitreous enamelled wire-wound 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.
