Aluminum Electrolytic Capacitors: ALS71H102DE400 Application Field and Working Principle

Aluminum electrolytic capacitors are components that are capable of storing charge and releasing electricity at a fraction of a second. In particular, the ALS71H102DE400 is an aluminum electrolytic capacitor made by the Japanese company NDK, featuring a working voltage of 400 V, a capacitance of 1 μF and a rated ripple current of 500 mA. It is certified RoHS complaint, making it a good choice for a wide range of applications.This capacitors main use is as a decoupling capacitor. This type of capacitor works by temporarily absorbing and releasing small amounts of energy, known as "ripple current". As a result, this capacitor is often used in power supply circuits and other circuits where there can be significant levels of electrical noise or interference, as it can help reduce or eliminate such noise. Additionally, its ability to absorb voltage spikes caused due to electrostatic discharge (ESD) makes it a great choice in both industrial and consumer electronics.Aside from the role as a decoupling capacitor, it can also serve as a coupling capacitor in many different kinds of circuits. Coupling capacitors are useful for connecting two circuits that are operating at different frequencies, and any capacitor with a low internal resistance is suitable for this task. Additionally, due to its large capacitance and low impedance, this capacitor is also suitable for high voltage applications where the capacitor needs to have a low reactance at high frequencies. In terms of its internal construction and working principle, the ALS71H102DE400 capacitor is a polarised aluminum electrolytic ca-pacitor. Its main components are two aluminum plates shaped like a cylinder or a can, with a sepa-rating separator and electrolyte between them. The positive plate is an aluminum foil, which is etched to form a large number of small protruding tablets on its surface. The negative plate is a band of thin aluminum rolled up on itself. When a voltage is applied across the capacitor, electromigrate ions from the electrolyte start thro-wing electrons at the positive plate, causing it to become more positive with respect to the nega-tive plate. This sets up an electric field between the plates, and this electric field causes not only an electrical charge to build up but also an electrostatic field. The strength of this electrostatic field can be adjusted simply by changing the applied voltage, which can control the capacitance of the capacitor.To sum up, the ALS71H102DE400 aluminum electrolytic capacitor is a versatile component with great capacitance and low impedance. Its ability to absorb and release spike currents and its suitability for a wide range of applications make it a great choice for use in power supply circuits, ESD prevention and more.
