METAL OXIDE FILM RESISTORS, FLAMEPROOF
ELECTRICAL AND MECHANICAL PERFORMANCE
ENVIRONMENTAL CHARACTERISTICS
1. Electrical and mechanical stability and high reliability.
2. Nonflame painting, Solvent proof, resistant to heat &
humidity.
3.
Annual shift is low for the strengthened metal oxide film.
4. Low noise can produce high resistance values which
wire wound resistors can not reach.

Note:
1. Too low or too high ohmic values can be supplied only case by case.
2. If high resistance values are required, we suggest using RDN series.
3. 0.22 ~ 9.1 are using alloy film.Ù
