Bypass (decoupling): Provide a low impedance path for some parallel components in the AC circuit. Coupling: As a connection between two circuits, it allows AC signals to pass through and be transmitted to -level circuit. The role of electrolytic capacitors in switching power supplies are: Blocking DC: The function is to prevent the passage of DC and allow the passage of AC. All capacitors are aluminum radial electrolytic type, with two leads on one side for easy PCB mounting and breadboard use. This design is ideal for compact layouts and stable performance. Filtering: Change the rectified wave into a smooth pulsating wave, close to DC. storage: store electrical and release it when necessary. Clearly Marked Values Capacitors feature printed capacitance and voltage markings to help reduce assembly errors and make troubleshooting and replacement more efficient., Manufacturer: Aundhegrtt
