Aluminum electrolytic capacitors are a type of electrochemical capacitor that uses aluminum oxide as a dielectric. Their capacitance values can range from less than 1µF to thousands of µF, and they have excellent ESR and leakage current characteristics. The ECA-1HM4R7B is a particular type of aluminum electrolytic capacitor which is designed for use in power supply applications. It has a rated capacitance of 1µF, a maximum working voltage of 4 volts, and a temperature range of -10℃ to 105℃. In this article, we’ll explore the application field and working principle of the ECA-1HM4R7B.

Application Field of ECA-1HM4R7B

The ECA-1HM4R7B is an aluminum electrolytic capacitor which is designed for use in power supply applications. It has a rated capacitance of 1µF, a maximum working voltage of 4 volts, and a temperature range of -10℃ to 105℃. Due to its low capacitance value and working voltage, the ECA-1HM4R7B is suitable for use in circuits where low voltage and low capacitance values are required such as DC/DC converter circuits, PFC circuits, and buck/boost converter circuits. In addition, the ECA-1HM4R7B can also be used in voltage detection and surge protection/prevention circuits where its low capacitance value and working voltage make it ideal.

Working Principle of ECA-1HM4R7B

As an aluminum electrolytic capacitor, the ECA-1HM4R7B works on the principle of an electrolyte being placed between two aluminum plates to form a capacitor. The capacitor consists of two electrodes, an anode and a cathode, that are separated by a thin layer of aluminum oxide. This aluminum oxide layer functions as a dielectric and allows current to flow between the electrodes when a potential difference is applied across them. When a potential difference is applied across the capacitor, a charge begins to flow and the capacitor is said to be “charged.” The capacitance of the capacitor is determined by the size and geometry of the electrodes, the type of electrolyte used, and the thickness of the dielectric layer. In the case of the ECA-1HM4R7B, its rated capacitance of 1µF is achieved through the use of an aluminum oxide dielectric layer.
