BC-1 wire wound resistor Close-up of BC-1 resistor BC-1 resistor side view BC-1 resistor top view
The BC-1 wire wound resistor features high resolution capability with a wide resistance range. It offers excellent heat resistance, humidity resistance, and wear resistance characteristics. Suitable for voltage and current adjustment in power equipment and circuits not exceeding 380V AC or 220V DC.
Technical Specifications
  • Maximum working voltage: 1000V (insulation voltage 2500V)
  • Temperature rise: 25-100W models ≤300K; ≥150W models ≤350K
  • Sliding travel: 25-50W models: 280±5°; ≥100W models: 300±5°
  • Linear deviation: Not greater than ±10% across entire travel
  • Control shaft rotation: 5,000 cycles within travel of not less than 90%
  • High temperature test: 40°C for 6 weeks (6 days), insulation resistance less than 1.5MΩ
The BC1 series of rotor-arm sliding wire porcelain disk variants are designed for voltage and current adjustment in industrial electrical equipment up to 500 volts. The resistor uses a round ceramic skeleton with constantan or nichrome wire as resistance material, coated with high-temperature enamel except for the sliding contact surface. Features a protective metal case with handwheel operation.
