Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors represent a type of capacitor that uses an electrolyte like liquid or paste, as one of its dielectric surfaces. Its structure consists of two aluminum foils, with an insulating material that separates them. The foil that serves as the anode is etched to swell it and give it a large surface area, thus increasing its capacitance. It is then impregnated with a liquid or gel of organic solvent, and finally a second aluminum foil is applied, this is the cathode.

228TTA080M

The 228TTA080M is an aluminum electrolytic capacitor that is designed for use in a variety of applications, such as power control, general electronics, motor control, and more. It has a voltage rating of 80V, a capacitance range of 0.1µF to 4.7µF, a lifetime rating of 5,000 hours, and a range of temperature options from -30°C to 105°C. It is RoHS compliant and offers a low profile design for ease of installation.

Application Field and Working Principle

The 228TTA080M aluminum electrolytic capacitor is an excellent choice for a variety of applications such as, DC-DC converters, power supplies, motor control circuits, switch mode power supplies, home appliances, industrial equipment, automotive, etc. It is also a suitable choice for AC line filtering, audio crossover networks, and signal shaping circuits where low ESR or frequency response is important. The capacitor is designed to store electrical energy, basically acting as a buffer between the supply voltage and the load, smoothing out transient voltages spikes, providing a steady output voltage at the terminals and reducing noise.When a voltage is applied to one terminal of the capacitor, the positive plate attracts electrons from the negative one, thus creating an electric field between them. The positive plate gets charged and the negative plate is discharged. This process continues while the applied voltage is maintained. The rate of charge and discharge of the capacitor is determined by its capacitance, which is the ability of a capacitor to store a given amount of electrical charge with a given voltage applied.

By taking advantage of its high capacitance, the 228TTA080M is capable of supplying energy to the load during brief power outages, therefore increasing the load\'s reliability and allowing it to run without interruption. It can also provide a steady output voltage even when the supply voltage is fluctuating and for this reason, it is often used to reduce noise in applications such as high frequency circuits. The capacitor also helps to extend the life of the components it is protecting by reducing thermal stress and limiting current inrush. In addition, the capacitor has low ESR and ESL for effective noise filtering.
