Tantalum - Polymer Capacitors are electronic components designed to store energy in an electrical field. The T540B107M003DH8510 capacitor is a monolithic, low-ESR, Polymer Tantalum type electrolytic capacitor specifically designed for use in automotive applications, such as power systems, telecommunications, and data processing.

Applications

The T540B107M003DH8510 capacitor is used in automotive applications due to its greater stability, robust construction and better temperature characteristics. This includes its use in power supplies, fuel systems and battery management. The durability and high reliabilty of this capacitor also makes it popular for applications in robotics and factory automation where it is used to maintain power in small computer systems.

The T540B107M003DH8510 capacitor is also suitable for filtering power and controlling current ripple in high frequency DC/DC converters, automotive ECUs (Electronic Control Units), audio devices and military applications due to its wide operating temperature range.

Working Principle

The T540B107M003DH8510 capacitor works by storing electrical energy in a dielectric medium between two conductors. It consists of a two-layer thin barrier of dielectric material between two metal electrodes. When the capacitor is charged by the current, a voltage is developed across the two electrodes. The voltage level developed is proportional to the charge stored in the device.

The dielectric medium in the capacitor is made from a particular polymer material that exhibits low equivalent series resistance (ESR) properties. This property allows for a better current ripple control and for a smoother power supply to the application.

The T540B107M003DH8510 capacitor is a leakage current type device, meaning that when a small charge is drawn from the device, it is replaced with the fresh charge from the outside. This allows the capacitor to reduce ESR and voltage overshoot.

The T540B107M003DH8510 capacitor also provides some level of protection against capacitor abuse due to its robust construction. There is also a “burn” protection feature which in case of overvoltage or an overload, can protect the capacitor circuit from damage.

Conclusion

The T540B107M003DH8510 capacitor is a robust and reliable high-performance polymer tantalum electrolytic capacitor. It is designed for applications in automotive and military technology, particularly in high frequency DC/DC converters, ECUs and audio devices. The capacitor is also suitable for use in power supplies, fuel systems, and battery management due to its stability, robust construction, and temperature characteristics. The device has a low ESR and a “burn” protection feature for overvoltage or overload protection.
