Tantalum Capacitors

Tantalum capacitors are a type of polarized capacitor components used in many electronic circuit designs. They are able to store and release energy when needed and they are highly reliable in operation and are quite small in size. The TPMU227K016R0030 is a surface mount, solid electrolytic chip style of tantalum capacitor with specification of 2.2 uF, 16V, 0.39 Ω and a rating of 0.5W. This capacitor is available as both a standard and a low ESR (equivalent series resistance) version.

Application Field

The TPMU227K016R0030 tantalum capacitor is used in many different applications and comes in a variety of sizes and configurations. It is often used in mobile phones, computers, consumer electronics and medical equipment. It is also widely used in automotive electronics, and is often chosen due to its high reliability in demanding applications. The low-ESR version of this capacitor is able to operate more effectively in large currents, which makes it suitable for applications such as boost converters, DC/DC converters, regulators, and other switching systems.

Working Principle

Tantalum capacitors are polarized devices, and they are most commonly built with a tantalum oxide cathode and an electrolyte anode. When voltage is applied to the capacitor, electrons are released by the cathode and attracted by the anode, which allows for the formation of an electric double layer between the two electrodes. This stored charge can now be released when needed. The tantalum oxide cathode of the TPMU227K016R0030 provides a high dielectric constant and low leakage to ensure the capacitor will store and release charge efficiently. The ESR (equivalent series resistance) of a capacitor determines the amount of resistance to current flow, which can affect its performance. The standard version of the TPMU227K016R0030 has an ESR of 0.39 Ω, whereas the low-ESR version has an ESR of only 0.29 Ω, making it much better suited for applications requiring large currents.

Conclusion

Tantalum capacitors, such as the TPMU227K016R0030, are effective polarized capacitors used in many different applications. They have a high dielectric constant and low leakage, allowing them to efficiently store and release energy when needed. The low-ESR variant of this capacitor is especially effective for applications requiring large amounts of current.
