THICK FILM CHIP RESISTORS

The CR series Thick Film Chip Resistors are manufactured by screening a metal glaze layer on a high grade ceramic body. The different resistance values are obtained by using different compositions of metal glaze. The end contacts are made to ensure optimum solderability. The resistive layer is then given a protective coating.

The CR series offer a wide range of power ratings from 1/20W to IW and are available in tolerance ranges of ± 1 % and ±5% % with insulation Resistance ≥ 1000MΩ. .Miniature size, excellent mechanical strength and electrical stability ensures reduced costs and enhances dependability.
