What is the use of gold aluminum shell resistor? Gold aluminum shell resistor has stable performance and low resistance value. Gold aluminum shell resistor uses ambient temperature:-55 ℃ ~ +170 ℃; Accuracy range: 5%, 2%, 1%. Gold aluminum shell resistance through to change its own resistance, so as to play the role of control circuit, in the circuit analysis, gold aluminum shell resistance can be used as a constant value resistance, but also as a variable value resistance. Gold aluminum shell resistors are made of nickel and chromium, alloy resistance wire wound on alkaline heat-resistant porcelain pieces and other high resistance, external heat, humidity, no corrosion and protective materials, ceramic packaging again, especially non-flame cement filler sealing. At present, the demand for gold aluminum shell resistors in the market is slowly expanding.
1. The resistance core adopts high temperature resistant ceramic flat tube, and the basic size of ceramic is determined according to the shell size. 2. The resistance wire is uniformly wound with high-quality electric heating alloy wire, and the grade and model of the alloy wire are determined according to the resistance value. 3. Sealing material: both ends are sealed with water sediment resin slurry (electronic insulating material), and aluminum plate is used to press the seal when the cement material is semi-dry, so that the aluminum plate and the cement material are integrated to prevent sand leakage. 4. Shell: High-quality industrial 6063 aluminum is used. The aluminum shell is anodized into fog silver. Sandblasting or wire drawing can also be used according to customer needs. 5. The outgoing line adopts UL AWM3122 white textile silicone rubber high temperature line (conventional temperature resistance 200 degrees, the highest temperature resistance 250 degrees)
