Introduction to Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, also known as an AL-cap or a polarized capacitor, is an electrical component composed of two metal foils separated by an electrolyte, which acts as an insulator when voltage is applied. It is a type of electrolytic capacitor, the most common type of capacitor used in circuit boards. The electrolyte, an aqueous solution of an alkali metal salt, contains a small amount of conductive ions that form a conducting path connected to the two foils.

Application Field and Working Principle of EGXE451ELL100MK20S

EGXE451ELL100MK20S aluminum electrolytic capacitors are designed for a wide range of applications,including consumer electronics, automotive, and industrial electronics. This particular capacitor has a capacitance of 100µF, a voltage rating of 16 V, and a rated temperature of 85°C. It also has ripple current capability up to 660mA, a high energy density, long life expectancy, and robust construction. The working principle of EGXE451ELL100MK20S is the same as that of all other aluminum electrolytic capacitors. As voltage is applied to the capacitor, a current passes through the electrolyte and forms a conducting film on the aluminum plates. This forms an electric charge, which is stored and released as needed depending on the current load of the circuit. As voltage is applied to the capacitor, the electrolyte and the plate develop a positive charge. This causes ions to move to the positively-charged plates, which creates a conducting path between the plates. This conducting path ensures that the capacitance remains constant regardless of the voltage applied to the capacitor. As the current builds up, the plates become completely charged. When the current decreases, the plate\'s voltage slowly drops, releasing the stored energy back into the circuit. In comparison to other types of capacitors, aluminum electrolytic capacitors offer advantages such as high capacitance, low ESR (equivalent series resistance), low leakage current, low ESR temperature coefficient, long life expectancy, and low dielectric absorption. Additionally, aluminum electrolytic capacitors have relatively low costs and are available in a wide range of sizes and voltage ratings.

Conclusion

EGXE451ELL100MK20S aluminum electrolytic capacitors are one of the most common types of capacitors used in modern circuits. They offer a number of advantages, including high capacitance, low ESR, low ESR temperature coefficient, long life expectancy, and low cost. While they are primarily used in consumer electronics, automotive, and industrial electronics applications, they can also be used in other circuits as well.
