Aluminum electrolytic capacitors are widely used in modern electrical systems due to their low cost, small size, and good performance. The ALS70H821DE450 is an aluminum electrolytic capacitor, one of the most popular types of aluminum electrolytic capacitors. It has a long life span and is suitable for a wide variety of applications. This article will discuss the applications and working principles of the ALS70H821DE450.

The ALS70H821DE450 belongs to the Surlyn DE family of aluminum electrolytic capacitors. Its features include a high capacitance tolerance, a long life, an operating temperature range from -40 to +85°C, and an Ohio Brass meets MIL-E-50154/1, UL746C E85293, and UL1411 & UL1412 requirements. It has a Polarized or Non-polarized version and is rated to a voltage of 450V. The size of the ALS70H821DE450 aluminum electrolytic capacitor is just 7.3×6.7mm, making it well suited for high-density circuit designs.

The applications of the ALS70H821DE450 aluminum electrolytic capacitor are mainly in the fields of medical equipment, automotive applications, telecommunications, and power supplies. It is a reliable and durable capacitance solution for these types of applications. The ALS70H821DE450 is also ideal for high power input capacitors used in power supplies and high frequency circuits.

The working principle of the ALS70H821DE450 aluminum electrolytic capacitor is based on the Faraday law of induction. In an electrolytic capacitor, electrodes are immersed in an electrolyte solution, and an electrical current is passed through them. As a result, an electrochemical reaction occurs in the electrolyte that causes ions to be deposited on the electrodes, forming a thin layer of oxide. This oxide layer creates a barrier between the negative and positive electrodes, thus providing capacitance.

The main components of the ALS70H821DE450 aluminum electrolytic capacitor are a foil anode, a alkaline cathode, a gel electrolyte, a non-polarized plastic case, and a pressure seal. The oxide layer on the anode and cathode foil is what provides the capacitance. The gel electrolyte then further enhances the capacitance. The pressure seal prevents leakage of the electrolyte. The plastic case protects the whole assembly from external shocks and vibrations.

In conclusion, the ALS70H821DE450 aluminum electrolytic capacitor is ideal for applications where a long life and high capacitance tolerance are needed. Its small size makes it well-suited for high-density circuit designs. It has a wide operating temperature range and is rated for a voltage of 450V. Its working principle is based on the Faraday law and uses an oxide layer to provide the capacitance. The components of the ALS70H821DE450 aluminum electrolytic capacitor are a foil anode, a alkaline cathode, a gel electrolyte, a non-polarized plastic case, and a pressure seal.
