T540D477K004BH87107280 Application Field

T540D477K004BH87107280 is a type of tantalum-polymer capacitor. Its application can be found in a variety of industries and applications, such as digital and mobile products, laptops, tablets, cell phones, flat panel displays, medical and military equipment, automotive electronics and more. As a type of capacitors, their main function is to store energy, filter out and buffer the noise of electronic systems to ensure the normal operation of electronic products.

T540D477K004BH87107280 Working Principle

The working principle of T540D477K004BH87107280 is simple and complicated, involving the principles of electricity, electronics, materials science and physics. Generally, it works by using two metal oxide electrodes sandwiched between two electrolyte layers and a tantalum body. When a voltage is applied, current flows from the anode to the cathode and an electric field is created in the capacitor, resulting in an electric charge stored in the capacitor. This electric charge stored in the capacitor is the capacitance of the capacitor. The capacitance is related to the area and distance between the two electrodes. The larger the capacitance, the more charge the capacitor can store and thus the higher the voltage it can withstand. The metal oxide and tantalum ensure that the capacitor is safe, free from electrolyte leakage, and has a long service life.

Conclusion

T540D477K004BH87107280 is a type of tantalum-polymer capacitor. Its application field varies in digital, mobile, medical and military products and more, and its working principle involves the principles of electricity, electronics, materials science and physics, involving two electrodes between two electrolyte layers and a tantalum body while an electric field is created in the capacitor. With its large capacity and high reliability, it is widely used as power storage device, noise filter and buffer to maintain smooth functioning of electronic systems.
