Tantalum Capacitors

The T495D227K006ATE100 is a type of capacitor known as a tantalum capacitor. This type of capacitor is used in electronic applications to store electrical energy. It is made from tantalum, a material that has a high capacitance-to-volume ratio and is extremely stable, making it ideal for groups of capacitors to be used in parallel or series in applications that require both high and low values of capacitance.

General Properties

Tantalum capacitors come in many different shapes and sizes. They range from very small sizes such as 0603 to significantly large sizes such T293D337K006A. Generally, the larger the capacitor, the higher the capacitance level. However, it is also important to keep in mind that larger capacitors also have more inductance, which can affect their overall performance.

Most tantalum capacitors have very low equivalent series resistance (ESR) levels and high ripple current ratings. This combination makes them ideal for applications that require low loss and high efficiency such as high switching frequency, high voltage afterglow, and linear motor controllers. In addition, they have very low equivalent parallel resistance (EPR) values, which can be beneficial where long voltage stability is required.

The T495D227K006ATE100

The T495D227K006ATE100 is a surface mount tantalum capacitor with a capacitance of 2.2 µF, an operating voltage rating of 6.3 volts, and an ESR of 0.040 Ohms. It is manufactured using two solid electrodes with a solution of tantalum pentoxide as the dielectric material. The size of the T495D227K006ATE100 is 0402, making it one of the smallest tantalum capacitors available.

The T495D227K006ATE100 has a high pulse endurance which makes it suitable for high-switching frequencies and circuits in which the components experience fast transitions. It also has a low ESR, which is beneficial in applications that require minimal energy loss. In addition, the T495D227K006ATE100 is electrostatically safe, which makes it suitable for use in low-leakage applications.

Application Fields and Working Principle

Tantalum capacitors are commonly used in electronic applications to store electrical energy. They are especially useful for applications that require a combination of high capacitance levels and low equivalent series resistance values. Some common applications include dc-dc converters, voltage regulators, and switching supplies. They can also be used in high current/charge applications, linear actuators, backlighting, and flashlights.

The T495D227K006ATE100 has a range of benefits that make it a popular choice for electronic applications. Its small size makes it ideal for high density applications that require high capacitance but limited space. Its low ESR values also make it beneficial in applications that require minimal energy loss. Its high pulse endurance makes it suitable for high-switching frequency applications, and its electrostatic safety makes it ideal for use in low leakage designs.

The working principle of a tantalum capacitor is relatively simple. It consists of two plates made from tantalum with a dielectric material between them. When a voltage is applied, the capacitor will store electrical energy in the form of an electrostatic charge between the two plates. The amount of charge that can be stored is determined by the capacitance level and the ESR of the capacitor.

Conclusion

The T495D227K006ATE100 is a type of tantalum capacitor that is ideal for applications that require a combination of high capacitance levels and low ESR values. Its small size makes it suitable for high density applications, while its high pulse endurance makes it suitable for high switching frequency applications. Furthermore, its electrostatic safety makes it an ideal choice for low leakage designs. It is a versatile component that can be used in a wide range of electronic applications.
