-- RESISTORS
Name:METAL OXIDE FILM RESISTORS
Type:

Description:

Through the developements of electronic equipements and computerized devices, it has been urging all kinds of compo-nents to minimization, light-weight, durability, high stability and reliability. To keep quality stable under high tempera-ture operation. the per unit film area shall take large load. Metal Oxide Film resistors is the one that can satisfy therequirements.
MOS:Small-sized metal oxide film resistors, use selected ceramic,with high performance which is suitable for compact sets.

 


  • Small in 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, can produce height resistance value which wire wound resistors can not reach.

  • Variety of packaging-bulk, taped and reel, cur and formed supplied.
