Aluminum electrolytic capacitors are widely used in various electronic products, among which ‘Snap-in’ aluminum electrolytic capacitors are one of the most consumed types. Almost all manufacturers provide ‘Snap-in’ type aluminum electrolytic capacitors in their product line. The ALS81C303NS200 is one such ‘Snap-in’ type aluminum electrolytic capacitor.

The ALS81C303NS200 aluminum electrolytic capacitor has a voltage rating of 100V, a capacitance value of 3300 μF and a ripple current rating of 8.4A. It also meets the automotive industry’s standards and is compliant with AEC-Q200. It is available in a -20/+105°C temperature range and is characterized with an extended life of 4000 hours at 105°C, which is significantly better than average life expectancy.

Application Field and Working Principle

The ALS81C303NS200 aluminum electrolytic capacitor is mainly used in automotive electronics applications such as alternators, headlights, wipers, gauges, and entertainment systems. It is often used in noise suppressing filter applications, DC blocking, and DC withstanding applications in power supply lines, and local decoupling applications with low voltage capacitances.

The working principle of the ALS81C303NS200 aluminum electrolytic capacitor is based on the principle of electrochemical capacitance. The capacitor consists of two metal surfaces separated by an electrolyte material. The metal surfaces are the anode and the cathode, and they have an electrolyte in between them. When a voltage is applied to the capacitor, electric charge is stored on the anode and cathode plates, and it forms an anode-cathode space charge layer that stores energy as electrostatic energy. The powerful capacitance of the capacitor is determined by the size of the anode-cathode space charge layer.

The ALS81C303NS200 aluminum electrolytic capacitor is constructed with snap-in cylindrical-type aluminum cases with either insulated or uninsulated end caps. The capacitor also has a low ESR (equivalent series resistance) of 20 mΩ, making it a good choice for high-efficiency and high-frequency applications. Furthermore, the capacitor’s self-healing ability prevents damage caused by excessive in-rush currents and extreme heat.

Aluminum electrolytic capacitors are widely used in many electronic applications because of their robust construction, long life, and high capacitance. The ALS81C303NS200 aluminum electrolytic capacitor is a reliable, high-performance, and cost-effective capacitor specifically made for automotive electronics. It is ideal for noise suppressing, DC blocking, and DC withstanding applications in power supply lines, and local decoupling applications with low voltage capacitances.
