INTRODUCTION |
| These Metal Oxide
Resistors offer excellent performance in applications where
stability and uniformity of characteristics are desired. They
provide lower cost alternatives to Carbon Composition Resistors
and General Purpose Metal Films. Metal Oxide also can replace
many low power General Purpose Wire wound applications, saving
both money and time, with shorter delivery cycles. |
|
 |
|
FEATURES |
- High power-to-size ratio for
significant space savings.
- Excellent long-term stability.
- Complete flameproof construction.
- High surge/overload capability.
- Wide resistance range : 1 Ω ~ 1MΩ
- Standard tolerance : ?% , ?%
