Aluminum electrolytic capacitors are designed for reversed DC voltage application to store electrical energy or filter noise in various industrial and consumer electric products. The ECA-0JHG471B is a type of aluminum electrolytic capacitor with reverse voltage ratings of 4.7 VDC. It has a minimum operating temperature of -40°C, a maximum operating temperature of 85°C, and a surge voltage of 6.3 VDC.

The ECA-0JHG471B is mainly used to filter and store electrical energy in various commercial, industrial, and consumer electric products. It can also be used as a buffer between stages in oscillators and amplifiers. The reverse voltage applied to the capacitor will depend on the application, but the voltage should not exceed the rated voltage.

The working principle of the ECA-0JHG471B is based on the capacitance of two metal plates with a dielectric material in between. When a voltage is applied to the plates, a charge moves from one plate to the other through the dielectric material. The capacitance is determined by the area of the plates, the distance between them, and the dielectric permittivity. The capacitance of this type of aluminum electrolytic capacitor is generally very high, so it can hold a relatively large amount of energy.

The ECA-0JHG471B also has two other important characteristics, the Equivalent Series Resistance (ESR) and the Leakage Current (LC) resistance. The ESR is determined by the internal fabrication of the capacitor and is a measure of the internal resistance that affects the capacitor’s ability to hold a charge. The LC is the amount of current that passes through the dielectric material when a reverse voltage is applied. This type of capacitor has low ESR and low LC resistance, which makes it suitable for applications requiring high capacitance and low leakage current.

The ECA-0JHG471B is widely used in various industrial and consumer applications, such as power supply filtering, switching regulator output filtering, oscillators, amplifiers, and more. In these applications, the capacitor will provide additional energy storage and filtering, effectively reducing the noise and ripple. It is important to note that this type of capacitor should not be used in applications requiring a higher voltage than its rated voltage.

Overall, the ECA-0JHG471B is a reliable and efficient aluminum electrolytic capacitor with reverse voltage ratings of 4.7 VDC and a temperature range of -40°C to 85°C. It is mainly used for filtering and storing electrical energy and has low internal resistance, low leakage current, and a high capacitance. This makes it suitable for various commercial, industrial, and consumer electric products. However, care should be taken to ensure that the voltage applied does not exceed the rated voltage.
