1. - aluminum shell resistor, aluminum shell resistor ( aluminum shell resistor) shell is made of aluminum shell , with heat dissipation groove on the surface, small volume, , strong overload capacity, weather resistance, and good accuracy. Good stability, good for mechanical protection, and more convenient for users to install
2. -quality metal resistors, excellent heat dissipation performance, small temperature coefficient, , ultra-small error, plus a temperature insulation sheet at the bottom of the +/- 1% resistor, the resistor plays a role of heat insulation under temperature conditions to prevent damage to the circuit board
3. - oxygen-free copper enameled wire wound inductor, resistant to 300 degrees temperature PC frame resistant to - impact, temperature resistant and not easy to burn
4. The treble part comes with a generation of protection module, which can instantly protect the treble under and prevent the treble from burning
