Aluminum electrolytic capacitors are components used in many applications to store electrical energy. SXR102M025ST is an example of an aluminum electrolytic capacitor that is commonly used in many digital applications. This capacitor has a capacitance of 102 mF, a voltage rating of 25V, and an ESR of 0.16 ohm. It has a long life expectancy of up to 1000 hours at 70°C, and has a ripple current rating of 1.4 A.

Application Field and Working Principle

SXR102M025ST is often used in power management circuits, charge storage circuits, and coupling and decoupling circuits. In such applications, the aluminum electrolytic capacitor can store electrical energy, reduce ripple noise, and filter out high-frequency noises. As this capacitor is a polarized aluminum electrolytic capacitor, the anode is the positive terminal and the negative terminal is the cathode. Electrolyte is filled between these two electrodes.

The working principle of an aluminum electrolytic capacitor is based on the Faradic principle. This principle states that a current and voltage can arise when two metal plates are separated, and then connected, immersed in an electrolytic solution. The two electrodes form a battery, with the anode being the positive terminal and the cathode being the negative terminal. When a voltage is applied, the anode becomes positively charged, while the cathode becomes negatively charged. This causes the ions of the electrolytic solution to leave the anode and migrate towards the cathode, which produces an electrical current. The anode also acts as a dielectric, allowing for a capacitance to be established. This capacitance can then be used to store electrical energy which is then released in the form of current.

SXR102M025ST aluminum electrolytic capacitor is specifically designed for use in high-frequency switching power supplies where high ripple currents, low ESR, and high capacitance are required. Such applications include switching power supplies, mobile phones, digital cameras, and other consumer electronics products.

Due to its low ESR, the aluminum electrolytic capacitor can effectively reduce ripple noise compared to other electric capacitors. However, due to its large effective capacitance, the SXR102M025ST aluminum electrolytic capacitor has a relatively large size. Therefore, when using this capacitor, special attention should be paid to the space design of the device. In addition, it is important to note that this aluminum electrolytic capacitor has a limited voltage rating, and should not be used beyond its specified voltage rating.

In conclusion, SXR102M025ST aluminum electrolytic capacitor is a common component in digital applications where a low ESR and high capacitance is needed. It is ideal for power management circuits, charge storage circuits, and coupling and decoupling circuits as a result of its effective capacitance and low resistance. The SXR102M025ST aluminum electrolytic capacitor should be operated within its specified operating voltage, as running above the specified voltage may reduce its life expectancy. Furthermore, due to its large size, special attention should be paid to the design of the device in order to ensure space efficiency.
