Feature: 1. High quality chip, strong performance and long service life 2. High-performance optocoupler with high switching speed and high withstand voltage 3. The screw is made of high toughness and anti-rust material, which is not easy to break and slide 4. The column is made of copper material and durable. 5. The shell is made of high temperature resistant flame retardant material. After the high temperature, the sign will not be deformed and wrinkled, and the joint is inseparable. 6. High-purity copper base plate is used to effectively increase the thermal conductivity by 1.5 times.
