Aluminum electrolytic capacitor (AEC) is a type of capacitor that uses an electrolyte in order to achieve a greater surface area of an electrode. AECs are used in a variety of applications, such as filtering audio signals, storing and releasing electrical energy, and for bypassing energy between two points. Aluminum electrolytic capacitors have become the main component in energy systems such as solar PV, solar water heating systems and electric vehicles.

ALS81A302KF350 is one type of Aluminum electrolytic capacitors. This capacitor features a low dissipation factor, low ESR, low temperature coefficient, high ripple current, low impedance, low ESR, and ultra-long life time. It has a wide range of applications, including coupling, smoothing, and energy storage. The product is available in various packages such as DIP, SMD and Snap-in and its rated capacitance ranges from 100 μF to 3200 μF. It is mainly used in signal conditioning and power supply, automotive electronics, switching and motor drives, LED lighting and security systems. And this particular capacitor is certified by both UL and RoHS.

The working principle of a Aluminum electrolytic capacitor is to use two metal plates that are separated by an electrolyte media. The plates are made of thin aluminum which has a coating of a material such as tantalum. An absorbed lubricant (in some cases), a gas inert to the electrolyte such as nitrogen or air, is present between the plates. When a direct voltage is applied, the electrolyte becomes polarized or charged. The ionic charge stored in the media forms an electric field that is proportional to the applied voltage. Thus, electrical energy is stored in the device as electrostatic field energy.

For absorbing and storing large amounts of energy, electrically polarized capacitors such as the ALS81A302KF350 are generally used. It’s optimized capacitance to ESR ratio make it ideal for high-ripple current applications. As mentioned earlier, it can be commonly found in signal conditioning, power supplies, motors drives, and LED lighting. In addition, this capacitor is also widely used in industrial applications like PLL and switching operations due to its high stability and reliability.

In conclusion, the ALS81A302KF350 is an Aluminum electrolytic capacitor that is commonly used in many applications. It features low ESR, low temperature coefficient, low impedance, and an ultra long lifetime. It is ideal for signal conditioning, power supplies, motor drives, LED lighting, and industrial applications. Its rated capacitance ranges from 100 μF to 3200 μF, and is available in various packages such as DIP, SMD and Snap-in.
