Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, are types of electrolytic capacitors that are made up of tantalum powder bonded as an anode and two metal layers bonded as a cathode. They are made with a high dielectric constant and offer higher capacitance values than other electrolytic capacitors. Their breakdown voltage is usually lower than that of other electrolytic capacitors, but is higher than that of non-polarized capacitors. Tantalum capacitors are also extremely small and lightweight, making them an ideal choice where space is an issue.

The 299D105X0025AB6 tantalum capacitor is an industry standard type of capacitor and is specifically designed for use in high voltage, high temperature, and high reliability applications. This capacitor is designed to offer lower ESR and improved performance in demanding applications such as those found in power supply and audio/video applications. It features a high capacitance value of 0.25µF and a working voltage of 16V.

Application Field and Working Principle

The 299D105X0025AB6 tantalum capacitor is designed for use in a wide range of electronic applications, from medical, military and aerospace, to audio/video, automotive, and telecom. It is used in boards that require a reliable and stable power supply, such as communication interface boards, current control boards, and voltage control boards. It is also used in audio/video, automotive ignition systems, power supplies, motor control boards, and digital circuits.

The 299D105X0025AB6 works on the principle of creating an electrical field between a pair of electrodes enabling the capacitor to store and release current. The anode and cathode electrodes of this capacitor are made up of tantalum and metal layers, which are separated by an electrolyte. The voltage applied across the terminals of the capacitor causes a current to flow through the electrolyte, thus resulting in a charge being stored on the anode. This stored charge is then released when the voltage across the terminals is reversed, thus allowing the capacitor to charge and discharge.

Tantalum capacitors such as the 299D105X0025AB6 are highly reliable in demanding applications, and offer superior performance, superior stability and enhanced ESR performance. They offer better performance compared to other types of capacitors, and are usually chosen for high voltage and high temperature applications where reliability and size are both factors.
