Tantalum capacitors are a type of electrolytic capacitor. They are polarized devices and usually consist of a tantalum metal electrode and an organic material, known as a polymer, as the other electrode. The T540D477K2R5BH8605 is a series of RoHS-compliant surface-mounted tantalum-polymer capacitors from Vishay Intertechnology. They have a 5.5V rated voltage, making them suitable for various industrial and consumer applications. These capacitors offer high capacitance values, in combination with very low ESR and excellent volumetric efficiency due to their low profile design.

The T540D477K2R5BH8605 capacitors use a tantalum anode wrapped with a conductive polymer cathode separator. The anode is formed from a high purity (99.99%) part metal powder that has been compressed and sintered until a disk is formed. This disk is then filled with a paste containing another metal powder from a different metal, such as palladium. The paste is activated chemically to form a very thin film of palladium which functions as a cathode, allowing the current to flow between the anode and the cathode when a voltage is applied. This is the same basic principle used in other types of electrolytic capacitors.

The T540D series of capacitors are designed for high capacitance values, high reliability and good temperature stability. They operate in both dc and ac circuits and offer a high energy density in addition to their small size and low profile. They provide high efficiency and long life performance. The tantalum anode and polymer cathode are designed to give excellent frequency responses, with excellent levels of stability over periods of time. They also offer low resistance and low dc leakage, making them suitable for a wide range of applications.

T540D477K2R5BH8605 tantalum-polymer capacitors are suitable for use in industrial applications where small size and low profile are essential, such as in switch-mode power supplies and notebook computers. They are also suitable for use in consumer electronics, since their low profile allows for the integration of circuitry into thinner and lighter products. They are also used in a variety of electronic communication and timing systems, where high precision, low power consumption and long service life are necessary.

The T540D477K2R5BH8605 series of tantalum-polymer capacitors are highly reliable, and offer excellent performance in a variety of applications. With their small size and low ESR, they provide an excellent level of efficiency in a range of different industrial and consumer applications. With their high capacitance and long life, they are a great choice for use in any device requiring reliable, high performance capacitors.
