SMD Multilayer ceramic chip capacitor is stable and has high capacitance. Laminated monolithic structure, excellent solderability and solder resistance, MLCC capacitors are suitable for reflow and wave soldering, various filtering and coupling circuits.
Multilayer ceramic chip capacitors are energy storage components. It stores electric charge in the form of electric field energy. In the circuit, this characteristic is often used to absorb the interference pulse signal in the circuit, smooth the surge current, store the electric energy, etc. When the two-terminal voltage of the chip capacitor is lower than the external circuit voltage (or power supply voltage), the external circuit charges it until it is fully charged, that is, its two-terminal voltage is equal to the external circuit voltage. When the voltage of the two terminals of the chip capacitor is higher than the voltage of the external circuit (or the power supply voltage), the chip capacitor discharges the external circuit until the voltage of the two terminals is equal to the voltage of the external circuit. If the external circuit voltage is zero, the chip capacitor will completely discharge the stored energy, that is, the voltage across the chip capacitor is zero. When the chip capacitor is just connected to the power supply, it is equivalent to a short circuit. Because the voltage at the two terminals of the chip capacitor is zero at this time, and the charging current is large.
