1. INTRODUCTION
The FCF series flame-proof Carbon Film Resistors
are manufactured by Coating a homogeneous film
of pure carbon on high grade ceramic rods, resistance
less than 10Ω 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 #1412 without
producing a fire hazard.
2.
FEATURES
Low cost, prompt delivery
High power-to-size ratio for significant space savings
Complete flameprrof construction-UL 1412
Excellent long-term stability
Wide resistance range : 1Ω ~ 10MΩ
Coating and marking resist Trichlorethelyne,
Freon, and other cleaning agents

Test! It may be helpful to everyone. Instead of using microcontrollers and ICs, you can use discrete components to implement the following functions!
The NiMH battery is 3.6V, and the low voltage protection is usually around 3V. When it is fully charged and used normally, it is discharged. When the LED discharges below 3V, it is protected and shut ...
