Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electronic components that store electric charge and are commonly used in all types of electronics circuits. They are widely used in consumer electronics, automotive, industrial, and many other applications, as well as for general purpose electronic applications. The E81D251VNN122MA63T capacitor is a type of aluminum electrolytic capacitor.

The primary components of an aluminum electrolytic capacitor are two conducting plates separated by a dielectric material. The plates are made of aluminum, which is coated with an oxidized layer called an anode. A liquid electrolyte, usually an acid or a base, is used to coat the anode. The electrolyte is a wet mixture of water and an ionic compound, usually a salt. This liquid electrolyte forms a layer of ions at the anode, which in turn form a barrier between the plates and isolate them electrically. The electrostatic buildup of the capacitor is created by placing a voltage across the plates, causing electrons to flow from one plate to the other, thus creating a charge on each plate.

The E81D251VNN122MA63T aluminum electrolytic capacitor is specifically designed for use in portable audio systems, particularly in mobile phone and laptop speakers. It has a nominal capacitance of 25µF, a rated voltage of 16V, and is specified by the manufacturer for a working temperature range between 40°C and 85°C. Popular brands of this capcitor include Panasonic, Sanyo and Nichicon.

The E81D251VNN122MA63T aluminum electrolytic capacitor has a long service life and is capable of operating in high temperature, as well as being extremely low in leakage current and having high working voltage. Its dimensions are 7.3-mm in length, 5.4-mm in width, and 4.5-mm in height. This small size allows it to be used in compact devices and circuit boards. The capacitor has an impedance that is consistent even at high frequencies, which is an advantage in audio applications.

One of the most important benefits of the E81D251VNN122MA63T capacitor is its high level of reliability and long service life. It has a rated life of 5,000 to 10,000 hours and can withstand up to 1,000 full discharge/charge cycles, making it ideal for long-term projects. It also has a low ESR (Equivalent Series Resistance) of 15 mΩ, which allows it to work well in audio applications. Furthermore, it has a Ripple Current of 105mA and a Surge Current capability of 300mA, meaning that it is able to handle high levels of incoming power without overloading.

In conclusion, the E81D251VNN122MA63T aluminum electrolytic capacitor is an ideal choice for use in portable audio systems, such as mobile phone speakers and laptop speakers. It offers a long service life, low leakage current, high levels of reliability, and a low ESR. Its small size allows it to be used in a variety of small electronic devices and circuit boards.
