| CARBON FILM RESISTORS FLAME-PROOF TYPE FCR Series |
| 1/4W, 1/2W, 1W, 2W, 3W FCR-25, FCR-50, FCR-100, FCR-200, FCR-300 |
| 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 
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 |
