TAJD687M002RNJ

Tantalum capacitors are widely used in a multitude of applications including portable electronics, mobile phones, and audio systems. Microwave tubes, computers, radar and aerospace equipment are some of the other major applications that use tantalum capacitors.

The TAJD687M002RNJ is a low profile chip tantalum capacitor with a matte tin finish that offers excellent temperature stability and improved noise characteristics. It is designed to handle high frequency switching, fast transients, board-level SMT (Surface Mount Technology) and high density arrays. The surface-mount TAJD687M002RNJ is constructed from tantalum powder, so it can handle high ripple currents without the risk of explosion. The design of the component ensures that there is no oxidation or corrosion of the internal electrodes. This makes them an ideal choice for harsh environments.

The capacitance of the TAJD687M002RNJ is 6.8 µF, with a standard working voltage of 2.5 V. It also has a capacitance tolerance of ± 20%. Its maximum operating temperature is 105°C, and its allowable equivalent series resistance is 2 ohms.

It should be noted that the TAJD687M002RNJ is not a long-life capacitor. It is designed to have a short lifetime of around 10,000 hours of operation. This short life span is due to the reactivity of the tantalum material and the use of solder as the connecting medium.

The TAJD687M002RNJ has a unique working principle. It works by storing electrical energy in an electric field between two metal plates, separated by a dielectric material. When the capacitor is charged, one of the plates of the capacitor is positively charged, while the other plate is negatively charged. The dielectric material between these two plates prevents electrical charges from going directly from one plate to the other. The electric field is created when negative and positive charges of electricity are separated.

When the capacitor is discharged, the charges stored in the electric field are released and the current flows through the circuit. The current is then proportional to the voltage that is applied to the capacitor.

The TAJD687M002RNJ is a highly desirable and versatile component, especially in applications with frequent voltage fluctuations and high ripple currents. Its high-quality construction and reliability, makes it a long time favorite among engineers and designers.
