Aluminum electrolytic capacitors are passive electronic components that are widely used in all kinds of circuits. They are known for their low cost, small volume, decent capacitance, great stability and good self-healing properties. Among these capacitors, EDK475M025A9BAA is one of the most popular ones.

The EDK475M025A9BAA capacitor has a general dimension of 4.7*7.5mm and a rated capacitance of 25µF at an attractive price. Its working temperature range is between -40°C and 105°C, and its nominal operating voltage can reach 25V. Besides, it is also equipped with a voltage surge capability of 2.25 times, a low ESR of 0.008 Ω and a high ripple current capability of 253mA.

The EDK475M025A9BAA is mainly used in power filtration and in coupling and decoupling circuits from the AC power line, such as television receivers, audio amplifiers, and DC-DC converters. It is also the perfect choice for space saving in consumer products like computers, mobile phones, and digital cameras.

The EDK475M025A9BAA\'s working principle is pretty simple. It is essentially composed of two aluminum foil plates, separated by a membrane formed by an electrolyte soaked paper. The two aluminum foil plates are connected to the positive and negative electrodes of the capacitor, respectively. When a voltage is applied to the capacitor, a layer of thin oxide film is generated on the surface of the foil plates. This thin layer of oxide improves the insulation capability of the capacitor and allows it to hold an electrical charge for a certain amount of time.

Although this oxide layer helps increase the capacitance of the capacitor, it gradually reduces the amount of charge that it can store and the capacitance of the device is destroyed eventually. Thus, EDK475M025A9BAA capacitors are expected to last for up to 5000 hours of working life.

To conclude, EDK475M025A9BAA is an aluminum electrolytic capacitor that has a high capacitance and relatively low operating voltage and ripple current. The device is perfect for consumer electronics and can withstand high temperatures, high surges, and high ripple currents. Lastly, its working principle is based on the formation of a thin layer of oxide between two aluminum foil plates that act as electrodes.
