2 Tips for Electronic Board Repair: Identifying Capacitor Capacitance (SMD) and SMD Transistor (SMD) In most new circuits, the components are SMD. Due to their small size, it is often difficult to read the values. It is possible that it has been erased or the component is damaged and the number cannot be read. For example, SMD transistors are among the components that are damaged the most. It is possible to identify the negative or positive type of transistor with a simple method. These transistors are often used as switches in the circuit, but they may also have an amplifying role. With the help of the method I described in the video, we can easily determine the type of transistor. Regarding SMD capacitors, the size and color of the capacitor often play an important role in identifying its value. Of course, there are different tables for reading the values. There are two companies that have listed these values ​​in full in a PDF file: AVX SMD Capacitor Company SMD Murata Company You can get complete information by searching these two companies for SMD components. Thank you for your support ❤️❤️❤️ ________________ I also have several training courses that can be purchased at a very reasonable price. By doing this, you will help me a lot so that I can continue these trainings. The best thing in electronics is to learn circuit analysis. The sooner you start, the more time you will have.
