In-depth analysis of car Farad capacitors, do you need them?

Capacitors are the basic components of electrical appliances, including the host, preamp, power amplifier, and even passive crossovers of speakers. Capacitors of various specifications and structures are ubiquitous, which shows their importance. In high-performance car audio systems, capacitors are also A very important part!

What is a car capacitor?

carFarad capacitors (CDA) have 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 operation efficiency of the power amplifier, and the sound quality is also degraded, resulting in distortion. However, if a car Farad capacitorcharges and discharges quickly, is added, when the power amplifier needs a large amount of power at the moment, 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. Prepare for the next "impulse" (amp power output), making the sound more powerful and less noisy at the same time!

Car Farad Capacitors (CDA) - can be compared to a lake of current with long life, fast charge and discharge. The car Farad capacitor (CDA) used in the power supply end of the car audio system is a thing that seems to be able to accommodate current. To put it bluntly, 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 running on the river, then the car Farad capacitor (CDA) seems to be between the source and the waterwheel. lake. When the waterwheel is working inefficiently, the normal activities of the river can be used to drive the waterwheel, but when the waterwheel needs to work under heavy load and quickly, the water flow from the source of the river often exceeds the supply, and even the waterwheel cannot be driven. At this time, if we build a lake between the waterwheel and the source, when the water from the source is too late to drive the waterwheel, we can use the pre-stored water in the lake to quickly replenish the waterwheel to maintain the operating efficiency of the waterwheel. This is the car Farad capacitor. (CDA) role.

Characteristics of Car Farad Capacitors

(1) The charging speed is fast, charging for 10 seconds to 10 minutes can reach more than 95% of its extra capacity;

(2) The cycle life is long, and the number of deep charge and discharge cycles can reach 10,000 to 500,000 times, and there is no "memory effect";

(3) The charging and discharging circuit is simple, no charging circuit like a rechargeable battery is needed, the safety factor is high, and the long-term use is free of protection;

(4) Good ultra-low temperature characteristics, the temperature range is -40℃～+70℃.
