    Tips: Functions of SMD Electrolytic Capacitor.

    • Blocking DC: The function is to prevent DC from passing through and allow AC to pass.
    • Bypass (decoupling): Provide a low-impedance path for certain parallel components in an AC circuit.
    • Coupling: As a connection between two circuits, allowing an AC signal to pass and travel to the next stage circuit.
    • Filtering: Turn the rectified sawtooth wave into a smooth pulsating wave, which is close to DC.
    • Energy Storage: Stores electrical energy and releases it when necessary.
