RCD Series CF resistors are designed for general purpose
applications. Multilayer coating and color band markings are
resistant to industrial solvents and humidity. New miniature sizes
enable significant space savings due to optimization of thermally
conductive materials. CF22 is 1/4W in 1/8W size and is designed
for mounting spans as small as 0.200” [5mm]. CF50A is 1/2W in
1/4W size, CF100S is 1W in 1/2W size. Manufactured in Far East.
