It is also often used in motor control systems, as well as aviation and telecommunications electronics. With its combination of low ESR, high capacitance, superior thermal performance, and low profile, the T541X107K030DH8620 tantalum-polymer capacitor is a great choice for these and many other industrial, commercial and consumer applications.

Working Principle

The T541X107K030DH8620 is a polymer tantalum capacitor electrostatically constructed from a tantalum anode and a special polymer based cathode. The anode is usually made from tantalum powder, pressed and welded into a solid structure. The cathode, on the other hand, is usually made from a special type of plastic film substrate material, coated with a special polymer solution. The anode and cathode are then connected to each other to form a capacitor.

The capacitance of the T541X107K030DH8620 capacitor is determined by the size of the dielectric material (plastic film) and its relationship with the anode and cathode. Because the anode is made from tantalum, it is the key factor in determining the level of capacitance. The design of the capacitor also impacts the capacitance rating and performance.

The working principle of the T541X107K030DH8620 is fairly straightforward. When a voltage is applied across the capacitor, the electrostatic force pushes electrons from the anode to the cathode, creating an electrical field between the two points. This field provides a charge storage effect, which is what gives capacitors the ability to store energy when voltage is applied to them.

When the voltage is removed from the capacitor, the electrons return to the anode and the electric field is reduced, effectively "bleeding" off the charge stored in the capacitor. This is why capacitors are often referred to as energy storage devices.

Conclusion

For its size, weight, long life expectancy and superior performance, the T541X107K030DH8620 tantalum-polymer capacitor is an excellent choice for a variety of applications. With its reliable performance, low profile and low ESR, this versatile capacitor can be used in automotive, AC/DC power supplies, motor control systems, aviation and telecommunications electronics and other industrial and consumer applications.
