Capacitors in electronic circuits is almost an indispensable energy storage element, which has cut off the DC, AC, to prevent low-frequency characteristics. Widely used in coupling, blocking, bypassing, filtering, tuning, energy conversion and automatic control circuit. 1, the filter capacitor: connected to the DC power supply between the positive and negative, to filter out the AC power components do not need to make DC smoothing. The general use of large capacity electrolytic capacitors or tantalum capacitors, but also in the circuit and other small capacity at the same time and other capacitors to filter out high-frequency AC. 2, Bypass capacitor: connected to the AC and DC signals in the circuit, the capacitor and then connected at both ends of the resistor or by a point across the circuit to a common potential for the AC signal or pulse signal to set a path to avoid the exchange of signals The component is attenuated by the voltage drop across the resistor. 3, decoupling capacitor: ^ w connected to the power amplifier circuit is positive and negative, to prevent the formation of positive resistance due to power supply parasitic shock caused. 4, the coupling capacitor: connected to the AC signal processing circuit, used to connect the signal source and signal processing circuit or for the two amplifiers connected between the level, to cut off the DC, so that the AC signal or pulse signal through the front and rear amplifier circuit DC working point without affecting each other. 5, pad capacitance and resonant capacitor: main capacitor series auxiliary capacitor, adjust it to make the oscillation signal frequency range smaller, ^ w can significantly improve the low frequency side of the oscillation frequency. 6, tuning capacitor: connecting the oscillation circuit in both ends of the resonant circuit, play a role in the selection of oscillation frequency.
