CARBON FILM DCR
SECTION 1
High stock levels
Zero-ohm link available
The DCR range is available in power ratings from 1/6W to 2W. All
product is taped, with special taping forms available as an option. All
product is manufactured to specifications ELA RS196A, JLS-C-6402
and IEC-115.
Typical applications will range from consumer products to
computing and automotive uses.
All DCR’s are recognisable by their pale beige colour, and easily
readable EIA colour coding.
