Welcome to our store! 1. These transistor bricks are made from high-quality plastic and have a long lifespan. 2. These bricks are characterized by excellent insulation, low weight, rust protection, and corrosion resistance. 3. Primarily used to secure transistors to prevent short circuits between the transistor shell and cooler. 4. The main function of transistor bricks is heat insulation: suitable for crystal lamps, diodes, and transistors where heat dissipation and insulation are needed. 5. Each set includes many flat bricks that can be used for a long time, so you don't need to run to the hardware store for a while. Transistor bricks are also called insulation particles, plastic bricks.
