Gold aluminum shell resistor, the shell is made of aluminum alloy (gold aluminum shell), with heat dissipation grooves on the surface, high power, high temperature resistance, strong overload capacity, weather resistance, high precision, standard low inductive resistance, high stability, strong structure, Its flexible multiple combination options are good for mechanical protection and convenient for installation and use. Moreover, it uses electronic potting glue to block, low density, high thermal conductivity, vibration resistance, no noise, weather resistance, corrosion resistance, etc. It is mainly used in current limiting protection circuits and measurement and control circuits to test aging power supplies, inverters, automotive LED lights, and automation , Equipment, audio, elevator, and frequency divider servo industries require harsh industrial control environments.
