199D476X9010DXB1E3

Tantalum capacitors are electronic components used to store electric energy. The designation "199D476X9010DXB1E3" describes the characteristics of a specific type of tantalum capacitor. This type of capacitor has a small container size, low ESL and high capacitance. It is especially suitable for complex power supply systems because of its low ESR (equivalent series resistance) and high capacitance.

Application Field

Tantalum capacitors of the 199D476X9010DXB1E3 type are commonly used in electronics, telecommunication, and millitary or aerospace equipment. Their small container size and low ESL makes them particularly suitable for use in complex power supply systems, such as switching power supplies, cyclic power supplies, and microprocessor power supplies. They can also be used in applications that require high stability, such as precision medical equipment and some automotive control systems.

Working Principle

A tantalum capacitor is a type of electrolytic capacitor that uses a solid electrolyte made of tantalum as the dielectric material. The two electrodes of the capacitor are formed by an oxide layer on the surface of the tantalum wire that acts as the anode and a layer of conductive material, such as graphite or aluminum oxide, that acts as the cathode. When a voltage is applied to the capacitor, an electrical current passes through the capacitor and causes a charge to accumulate on the surface of the anode, creating an electric field. The dielectric material, usually the tantalum, then allows electricity to pass through, creating an electric current. This current is then stored and discharged as needed in the circuit.

The design of the 199D476X9010DXB1E3 type of tantalum capacitors makes them an ideal choice for complex power supply systems. The low ESL (equivalent series inductance) helps reduce power losses, while the low ESR (equivalent series resistance) ensures that the capacitor can handle high voltages without suffering from electrical breakdown. In addition, the high capacitance of these capacitors ensures that power can be stored and used efficiently in the circuit.

Conclusion

Tantalum capacitors of the type 199D476X9010DXB1E3 are a highly reliable and efficient choice for many power supply systems. Their small container size, low ESL, and high capacitance make them an excellent choice for circuits that require high voltage stability, such as precision medical equipment and some automotive control systems.
