Aluminum Electrolytic Capacitors General Introduction

Aluminum electrolytic capacitors, also known as electrolytic capacitors, are special types of capacitors that use a liquid electrolyte to store energy. Electrolytic capacitors are generally characterized by their large capacitances that can range from 1 μF (10−6farads) to thousands of microfarads. They have high voltage ratings and large energy storage capabilities which make them ideal for power supply applications. They also have relatively low series resistance and ESR, so they can be used as an effective low-loss filter in a circuit.

ALS81C103QM350 Application Field and Working Principle

The ALS81C103QM350 Aluminium Electrolytic Capacitor is a high-capacitance, high temperature aluminum electrolytic capacitor with a long rated life of 5000 hours. It has an operating temperature range of -40 to 85°C, rated voltage of 35V and a capacitance of 1000 μF. This type of aluminum electrolytic capacitor is used in applications that require a large amount of energy storage, such as DC motors, UPS systems, and power supplies, and have a relatively low resistance.

The working principle of aluminum electrolytic capacitors is similar to that of other types of capacitors. When an electrical voltage is applied, electrons are forced to move from one side of the capacitors, the cathode, to the other, the anode, separated by an electrolyte material. This movement of electrons creates a buildup of electrical charge which capacitors are able to store. Depending on the size of the capacitor, the number of electrons and electric potential can increase or decrease. With increased capacitance, the more electrons and higher the electric potential, stored in the capacitor.

The structure of an aluminum electrolytic capacitor is simple. It has two metal plates sandwiched between an insulator. One plate is the anode, which is also the outer metal plate, and the other is the cathode. The insulator is an electrolyte material, typically an oxide of aluminum which is created when a thin layer of aluminum is anodized. The aluminum oxide material between the anode and cathode helps to prevent a direct current connection from occurring. This is why aluminum electrolytic capacitors are referred to as "non-polarized", because the two ends look alike and can be connected regardless of their orientation.

The ALS81C103QM350 aluminum electrolytic capacitor has a high temperature rating of 85°C and can store a large amount of energy, making it ideal for power supply applications. It can also be used in high frequency circuits with strict requirements of low equivalent series resistance (ESR) and low equivalent series inductance (ESL) due to its high capacitance. The capacitor is also recommended for use in harsh environments due to its long rated life of 5000 hours, wide operating temperature range and high voltage rating.

Conclusion

The ALS81C103QM350 aluminum electrolytic capacitor is a reliable and high temperature device with a high capacitance and long life that makes it suitable for use in power supply applications. It also provides good performance in high frequency circuits due to its low equivalent series resistance and equivalent series inductance. Its wide operating temperature range ensures reliability even in harsh conditions. This makes the ALS81C103QM350 capacitor an ideal choice in applications that require high energy storage.
