Aluminum electrolytic capacitors (AECs) are the most popular type of electrolytic capacitors, widely used due to their relatively low cost, high capacitance, and availability in a wide range of package sizes. Among AECs, HR101223U050CE2B is specially designed for power supply and audio applications. This article is about its application field and working principle.

The HR101223U050CE2B petal-style capacitor can offer a low impedance and a wide working temperature range ranging from -40°C to +105°C. Its features include a very low ESR of 2.8 mOhms, a high ripple current of 6.96 A RMS, and an endurance life of 3000 hours at +105°C. These features make the HR101223U050CE2B capacitor suitable for use in high power applications such as power supplies, DC-DC converters, audio amplifiers, automotive electronics and lighting applications.

AECs are electrolytic capacitors that feature an anode made of aluminum/aluminum alloy or a metal-oxide layer. This layer helps the capacitor store electrical energy, while the electrolyte helps the capacitor accept and release charge. The electrical charge is stored thermally in a dielectric oxide layer, which is an oxide layer formed at the anode surface when a voltage is applied between the anode and the electrolyte. This oxide layer prevents charge from leaking back into the electrolyte and also helps the capacitor store the energy over time.

AECs consist of a positively charged anode, a negatively charged cathode, and a dielectric layer in between. When an AEC is charged, in the anode the positive charge accumulates over the dielectric layer. This charge attracts electrons from the cathode, which leads to an increase in the negative charge on the cathode. This creates an electric field across the dielectric, which leads to the storage of the electrical charge.

The HR101223U050CE2B petal AEC capacitor is a reliable, safe, and effective device for power conversion in a wide range of applications. It is widely used due to its low cost, high capacitance, and wide operating temperature range. Its features make it suitable for use in high power applications such as power supplies, DC-DC converters, audio amplifiers, automotive electronics and lighting applications.
