Tantalum Capacitors

Tantalum capacitors are solid electrolytic capacitors that use tantalum as one of the electrodes. It is characterized by the use of a semiconductor-based oxide film as the dielectric material, meaning that they are polarized, and the use of tantalum as the anode. The anode is either a made of a rod shape of tantalum powder, and a solid anode consisting of sintered tantalum anodes; the latter having a higher capacitance.

591D227X0010D2T20H Application Field and Working Principle

The 591D227X0010D2T20H is a medium-sized, surface-mount tantalum capacitor. It is a polarized, non-electrolytic component. It is designed for applications ranging from DC/DC converters to power supplies to communications, automotive, and consumer electronics. It is also used to increase the stability of power supply circuits by providing surge current capacity to reduce uncontrolled fluctuations in voltage or current.

The 591D227X0010D2T20H is composed of two electrodes, one of which is a polarized tantalum anode and the other a non-polarized cathode. The anode is made of a sintered rod shape of tantalum powder, and the cathode is made of a conductive manganese dioxide as the electrolyte. When a voltage is applied to the terminals, electrons from the anode travel through the dielectric and onto the cathode. This process is called Faraday\'s Law of Electrolysis. As a result, an electric field is established between the anode and the cathode and forms a capacitor.

The working voltage of the 591D227X0010D2T20H is 20 volt. Its maximum operating temperature is 85°C. Its capacitance value is 470uF. This capacitor is designed specifically for high-frequency applications. It provides excellent frequency and temperature stability. It is RoHS2 compliant and UL certified. The 591D227X0010D2T20H is a highly reliable, long-lasting capacitor designed for use in many power applications.
