Aluminum electrolytic capacitors, or aluminum electro capacitors, are passive electronic components composed of a pair of conductors separated by an insulating layer, offering storage of energy, filtering, blocking, and DC voltage decoupling. The model 80D471P200KD2DE3 belongs to this category. It is a long-life type capacitor with a voltage rating of 200 VDC and capacitance of 471 μF at 85°C.

Application Field and Working Principle

The 80D471P200KD2DE3 works as a efficient energy storage element, to absorb or release images of electrical energy. It can be used in audio system power supplies, signal processing systems, and AC and DC coupling/decoupling circuits. It is suitable for high frequency and high current applications, such as power conditioners, switch mode power supplies, inverters, and various electronic circuits. The working principle behind the capacitor is that when a voltage is applied, charge accumulates on the two plates in either a positive or negative fashion, creating a potential difference inside the capacitor.

When an alternating current passes through the capacitor, the plates charge and discharge very rapidly, and the capacitor behaves as an open circuit. Eventually, the capacitor\'s capacitance and efficiency will be reduced due to the electrical leakage, although the majority of capacitors are designed to be very robust and long-lasting. It is this rapid charging and discharging that helps to filter out certain frequencies when they are applied to audio systems and power supplies.

This 80D471P200KD2DE3 aluminum electrolytic capacitor consists of an anode of aluminum foil with an oxide layer of aluminum, and a cathode of aluminum-alloy foil. It is an electrolyte-based capacitor, which is characterized by its relatively high capacitance, low cost, and fairly wide temperature range. It has good ripple current capability, making it ideal for AC or DC line filtering, and is capable of withstanding high voltage transients without damage.

The electrolyte absorbs the charge on the aluminum plates, which are spaced by the insulator. This forms an effective barrier between the two plates as well as between the electric field and the electric field of the electrolyte. It is the electric field of the electrolyte that draws the charge and stores it, creating a step change from the initial voltages to the end-state voltage.

This process of charging and discharging makes it ideal for audio system power supplies, and AC and DC coupling/decoupling circuits. It is also reliable and relatively low cost, making it a popular choice in a wide variety of applications. As aluminum electrolytic capacitors go, the 80D471P200KD2DE3 is a good choice for any audio or power related circuit.
