Item No. : Metal Oxide Film Resistors
 |
 |
Description:
- Small size comparatively.
- Electrical and mechanical stability and high reliability.
- Nonflame painting , "SOLVENT" Proof, resistive to heat & humidity.
- Annual shift is low for the strengthened metal oxide film.
- Low noise and high resistance value which wire wound resistors can not reach.
