Aluminum electrolytic capacitors are one of the most common types of capacitors found in circuits. The UPW1E390MDD6TE is no exception. This aluminum electrolytic capacitor is commonly used in applications where high capacitance and low ESR (Equivalent Series Resistance) are needed. In this article, we will discuss the application field and working principle of this capacitor.

Application Field and Working Principle of the UPW1E390MDD6TE Capacitor

The UPW1E390MDD6TE Capacitor is mainly used in switching power supplies, consumer electronics, home appliances, switch mode power supplies, AC/DC and DC/DC converters, and other electronic circuits where high capacitance and low ESR are required. This capacitor has a capacitance of 390 μF with a maximum rated voltage of 16 VDC. It has a power rating of 5W and an operating temperature range of -40°C to 85°C.

This aluminum electrolytic capacitor has an anode made up of aluminum foil and a cathode made up of a porous metal or carbon film. The anode and the cathode are separated by an electrolyte, which is usually a gel or liquid containing an ionic compound. When a voltage is applied to the capacitor, the anion forms an oxide layer on the anode, which acts as a barrier and prevents the anions from moving freely. This, in turn, causes the capacitor to act as a filter, reducing the amount of energy it stores and releases over time.

In the UPW1E390MDD6TE, the anode and the cathode are separated by a separator composed of an insulating and impenetrable sheet. This separator prevents short-circuiting of the capacitor and helps to maintain a uniform charge distribution throughout the capacitor.

The UPW1E390MDD6TE has a leakage current of 0.2 µA and an ESR of 0.12 ohms. The ESR rating indicates the amount of resistance to AC current through the capacitor, so a lower ESR indicates a less noisy capacitor. This makes the UPW1E390MDD6TE an ideal choice for applications that require low noise.

Overall, the UPW1E390MDD6TE is an excellent choice for applications in which high capacitance and low ESR are required. The fact that it has a leakage current of 0.2 µA and an ESR of 0.12 ohms makes it a great option for applications where low noise is favored. This capacitor has earned a solid reputation for being reliable and long-lasting due to its superior construction and materials.
