Automotive audio capacitor refers to the electrolytic capacitor used in automotive audio auxiliary circuit. It is an auxiliary component for high-end car audio CD player and MD machine to improve audio restoration quality. There are three main functions in the circuit.

First of all, it can achieve the function of filtering. Because the capacitor has the characteristic that the voltage at both ends of the electrode can not change suddenly, the noise wave in the power supply is absorbed by the capacitor, so that it is suppressed before the power circuit enters the host and amplifier circuit of the car audio.

The second is the effect of signal coupling. The basic function of a capacitor in a circuit is to allow only alternating current to pass, not direct current to pass through.

The audio information signals flowing in the main unit and power amplifier of automobile audio are AC signals within a certain frequency range. Only when the AC signals form a loop can they be passed and amplified.

The function of capacitor is not to change the DC parameters of the circuit, so that the circuit AC path more smooth, so that the audio signal in the very weak signal can also be amplified, because the signal loss is smaller, the sound quality is higher.

In addition, the most important function of car audio capacitor is energy storage. The energy storage function of the capacitor also makes use of the characteristics that the voltage at both ends of the capacitor can not produce sudden change. When the power amplifier outputs high power energy, due to the energy storage function,

It can make full use of its fast dynamic characteristics to supplement the power amplifier circuit, reduce the instantaneous power supply voltage drop, and create necessary working conditions for the normal operation of the power amplifier.
