Tantalum capacitors are one of the most common electronic components in the world. They are widely used in electronic products such as laptop computers, cell phones and circuit boards. The T95R686M025CZAS is one such tantalum capacitor. It is a surface-mountable, chip-shaped capacitor with a capacitance of 6.8µF (microfarads).

Construction and Properties

The T95R686M025CZAS is constructed from a sintered tantalum pellet and two polyester film dielectrics, which are sealed with epoxy resin. The pellet functions as the anode and is affixed on the ceramic base, while the polyester films serve as the cathode. This capacitor is designed for rated voltages up to 10V and ensures the highest temperature stability. It also comes with a 6.3mm pitch and tin-plated termination.

The tantalum capacitor has excellent electrical characteristics, which include excellent volumetric efficiency, superior frequency response, low series resistance (ESR) and high ripple current. It also has a low leakage current and low inductance, making it suitable for high-frequency operation. Furthermore, the capacitor is not prone to failure, providing reliable and long-term performance.

Application Field and Working Principle

The T95R686M025CZAS is typically used in circuit boards, as it is small and light and can save space. It is widely used in audio, video and other consumer electronics as a filter capacitor. It is also used as a bypass capacitor for power supplies, owing to its low ESR and high ripple current rating.

The working principle of a tantalum capacitor is based on Faraday\'s law of electrolysis. When a potential difference is applied across its anode and cathode, the anode gains electrons from the electrolyte solution in the electrolyte reservoir, forming a layer of electrolyte oxide on its surface. This oxide layer acts as a dielectric medium, allowing the capacitor to store and release electrical charge.

The T95R686M025CZAS is a reliable capacitor that provides features like low ESR and high ripple current, making it suitable for a wide variety of applications. It is small and lightweight, making it easy to install in a variety of devices. Furthermore, it has excellent electrical properties, providing reliable performance and long-term service life.
