Aluminum electrolytic capacitors are the most commonly used capacitors in electronic applications. They store energy in the form of electric field, and are composed of a metal conductor coated with an insulating material. The ALS71H202KE400 is an aluminum electrolytic capacitor typically used in various applications. In this article, we will discuss its application field and working principle.

The ALS71H202KE400 is a radial leaded aluminum electrolytic capacitor with tolerance of ±20%. It is rated at 85°C, having a capacitance range of 100uF to 470uF and a voltage range of 25V to 450V. It has a temperature range of -55°C to 85°C and a life expectancy of 3,000H at 85°C. The ALS71H202KE400 is designed with a robust insulation coating to offer reliable operation even in extreme temperatures. This capacitor is widely used in the power, automotive and industrial markets.

The ALS71H202KE400 is mostly used in power applications such as voltage stabilization, noise suppression, ripple elimination, and high voltage suppression. It is also used in switching power supplies, DC-DC converters, and UPS systems. In automotive applications, ALS71H202KE400 is often used in navigation and infotainment systems, temperature control systems, cruise control, and anti-lock brakes.

The ALS71H202KE400 works in the same way as any other aluminum electrolytic capacitor. A dielectric oxide layer is formed between two metal plates. This layer separates the plates and creates an insulating barrier between them. The oxide layer creates a strong attraction between the plates, which forms an electric field. When an electric current is applied, the charges in the electric field move or rearrange themselves to form an electrical charge at the plates. This charge is then stored in the capacitor.

The amount of charge stored in the capacitor is determined by its capacitance. This capacitance is determined by the size and value of its plates, distance between them, and by the dielectric material used. The ALS71H202KE400 is designed with an improved dielectric layer that is more reliable than many other capacitors. The enhanced insulation provides superior heat resistance and reliability.

The ALS71H202KE400 also offers good electrical characteristics such as high reactance and capacitance retention over a wide temperature range. It also offers a low ESR and a wide frequency range with excellent input capacitance. The overall performance of ALS71H202KE400 makes it an ideal choice for many electrical and electronic systems.

In conclusion, the ALS71H202KE400 is an aluminum electrolytic capacitor that has many applications in various industries. It has excellent electrical characteristics such as high reactance, low ESR and excellent capacitance retention. It is also able to withstand extreme temperatures, making it suitable for many applications. This makes the ALS71H202KE400 capacitor a great choice for many electrical and electronic systems.
