Tantalum capacitors, sometimes known as Ta–Cs, are a type of electrolytic capacitor. Like traditional electrolytic capacitors, tantalum capacitors possess a cathode, anode, and dielectric. They are valued for their high capacitance, small size, and low cost. The T95Y686M004CZSL is one of these capacitors, with an application field and working principle that is important to understand.

T95Y686M004CZSL is a surface-mount polymer tantalum capacitor with a high capacitance of 680uF, a CV of 6.30V, and an ESR of 1.6 mR. It is a small size (0.400\'\' X 0.400\'\'), making it ideally suited for portable devices and other circuits where size is a critical factor. The capacitor is also extremely economic and relatively easy to manufacture.

It is typically used in applications requiring a high ripple current and large DC voltage ratings. Examples may include power supplies, personal computers, consumer electronics, cameras, CD/DVD players, and other devices that contain a mix of AC/DC power converters. The capacitor can be found in precision audio power amplifiers, filters, and signal conditioning applications, where the device’s high current and small voltage rating are a valuable asset.

The working principle behind Tantalum capacitors is much the same as with other electrolytic devices. The capacitor is made up of two Polarity plates of different conductors – an anode and cathode – which, when voltage is applied across them, develops a charge between them. The charge is then stored in the dielectric between the two plates. The dielectric material, in the case of the T95Y686M004CZSL, is a tantalum pentoxide film. This dielectric material has a greater capacitance than many other electrolytic materials, such as aluminum oxide, and is also a great deal more stable over temperature.

The capacitor itself acts like a very small battery, slowly releasing a current as voltage is released. This current, or charge, is then held in the capacitor until the external voltage reverses the process, filling the capacitor with a current of the same frequency again. When the current is reversed, the dielectric absorbs the energy and releases it back when the voltage is in the opposite direction. This process ensures the capacitor can store energy for long periods of time, and is a key component of how T95Y686M004CZSL delivers such high performance.

T95Y686M004CZSL capacitors have many advantages over traditional electrolytic caps in that they are typically lower cost, smaller in size, and deliver better performance. As such, they are seen across a wide range of digital and analog electronic systems, in particular those found in consumer portable devices, where size and performance is of great importance.
