The CCR-02 from Nova Elektronik is a carbon film resistor kit. It contains 1110 resistors, that cover 48 different resistance values between 10 Ω to 1 MΩ. The kit consists of CFR25 resistors from Yageo (or another suitable alternative). The Yageo CFR series are constructed from high grade ceramic rods coated with a homogenous pure carbon film. Connecting electrolytic copper leads are welded to the end caps after a helical groove is cut into the resistive layer
Carbon Film resistors typically get used in higher temperature applications. Together with a higher voltage capability they can also be used in pulse applications and are found in markets such as medical, power supplies and test and measurement.
