| ♂ Features |
Through the development of electronic
equipments and computerized devices, it has been urging all kinds
of components to miniature, light-weight, durability, high stability
and reliability. To keep quality stable under high temperature
operation, the per unit film area shall take larger load.
Metal
Oxide Film resistors is the one that can satisfy the requirements.
It is also available for small-sized metal oxide film resistor, using
selected ceramics, perform as good as normal size. |
|
1 Electrical and mechanical stability
and high reliability.
2 Nonflame painting, "Solvent" proof, resistant to heat
& humidity.
3 Annual shift is low.
4 Low noise:can produce high resistance values which wire wound
resistors can not reach. |
