What is the effect of car farad capacitors on audio?

How important is the car Farad capacitor (CDA) to the car audio? Maybe readers only know the large capacitor that is installed on the power supply end of the audio system and has a voltmeter attached to it, but in fact, the capacitor is the basic component of the electrical appliance, including the host , power amplifiers, and even the forced crossover of speakers, capacitors of various specifications and structures are everywhere, and their importance can be seen to be extraordinary!

The car Farad capacitor (CDA) fast, charging and discharging current is used in the car audio system. As the name suggests, it is a thing that can accommodate current. For example, if the car generator and battery are regarded as the source of river water, the current is regarded as a river, and the power amplifier is regarded as a waterwheel that uses the river to operate, then the car Farad capacitor (CDA) is like between the source and the waterwheel. lake.

In addition, the car Farad capacitor (CDA) has the characteristics of long life and fast charging and discharging speed. When the power amplifier is operating at high load, the instantaneous current flow is quite large. At the same time, the car generator and battery may not be able to supply power in time, resulting in a decrease in the operating power of the power amplifier and a consequent loss of sound quality. However, if a car Farad capacitor (CDA), which charges and discharges quickly, is added, when the power amplifier needs an instant large amount of power, it can maintain a stable power supply for the power amplifier at the moment when the generator and the battery are too late to supply power, and then quickly supply the power from the generator terminal. Fully charged and ready for the next "excitement" (amplified power output).

In addition, some companies in Japan are actively developing products that can save energy and reduce environmental load. Among them, ultra-large capacity is a representative environmentally friendly product, which can provide a variety of products with large capacity ranging from several hundred F to more than 3200 F.

As mentioned above, the super-capacity is different from the secondary battery, there is no chemical reaction, and only the ions on the surface of the activated carbon are physically absorbed to store energy, so it has the following characteristics:

1. Slow aging, capable of charging and discharging millions of cycles.

Second, the output density is high, which can realize rapid (large current) charge and discharge.

3. High charging and discharging power, even if the output density is 1KW/kg, more than 95% of the output power can be obtained.

Fourth, because no heavy metals are used in the constituent materials, it is an environmentally friendly product.

5. The safety is high when abnormal, even if there is an external short circuit, there will be no trouble.
