INTRODUCTION |
The FCR series
flame-proof Carbon Film Resistors are manufactured by Coating a
homogeneous film of pure carbon on high grade ceramic rods,
resistance less than 10 Ω have an electroless deposited nickel
film, and are coated with layers of gray color flame-proof
lacquer.
These resistors meet overload tests in accordance with UL
specification |
|
 |
|
FEATURES |

- High power-to size ratio for
significant space savings.
- Complete flameproof
construction-UL 1412.
- Excellent long-term stability.
- Wide resistance range : 1Ω ~ 10MΩ
- Standard tolerance : ?%
