Wide resistance range: 1Ω to 5KΩ
Excellent humidity resistance and overload capacity
Multiple winding options for different resistance values
High-quality resistance alloy wire construction
Non-flammable resin coating for safety
Available in single, dual, triple, and quad potentiometer configurations
Customizable ceramic materials and knobs
5-7 day production cycle
Construction Details
The BC1 rotor-type resistor features high-quality resistance alloy wire wound around a C-shaped ceramic ring. The entire resistance ring, except for the sliding contact surface, is coated with non-flammable resin paint. After special electronic adhesion treatment, the winding resistance ring is fixed on a circular chassis and baked at high temperature before assembly with hardware accessories and adjustment parts.
