Tantalum capacitors are an important component in the electronics industry, providing a reliable and efficient means of storing or filtering electricity. The TAJY687K002RNJ is a popular model of tantalum capacitor, used in a wide range of electronic applications. In this article, we will look at the application field and working principle of the TAJY687K002RNJ.

The TAJY687K002RNJ is a surface mount tantalum capacitor, designed for use with medium voltage applications. It has a capacitance of 10 to 47uF, a leakage current of 25uA, and an operating temperature range of -55 to +105 degrees Celsius. It is available in several lead configurations, including 0.039” and 0.062” pitch leads. The TAJY687K002RNJ is commonly used for power input and output smoothing, filtering, and decoupling.

The TAJY687K002RNJ uses a tantalum oxide anode to achieve its low ESR characteristics. Tantalum oxide anodes are created through the oxidation of tantalum material. This oxidation opens up many small pores in the material, creating a thin film of tantalum oxide. By connecting this thin film to a capacitor\'s electrodes, a low ESR is achieved. This low ESR contributes to the capacitor\'s improved ripple current and frequency characteristics.

The electrolyte used in the TAJY687K002RNJ is a mix of organic acid, passivating agent, and water. This mixture enhances the thermal stability of the capacitor, allowing it to handle higher temperatures. The organic acid reacts with the electrodes, creating a barrier between them, which prevents the electrolyte from interacting with the anode. The passivating agent prevents any type of corrosion in the electrolyte, while the water is used to dissolve the electrolytes.

The working principle of the TAJY687K002RNJ is similar to that of other capacitors. When the capacitor is connected to a power source, electrons will move from the negative terminal to the positive terminal. This movement of electrons forms an electric field, which causes the capacitor to store electrical energy. When the power source is removed, the electrons are allowed to flow back to the negative terminal, releasing the stored energy. This principle of storing and releasing energy is what makes capacitors a versatile and efficient power source for many different applications.

In conclusion, the TAJY687K002RNJ is a surface mount tantalum capacitor, offering high efficiency, low ESR, and wide temperature range. It is used for power input and output smoothing, filtering, and decoupling, and its working principle is similar to other capacitors. The TAJY687K002RNJ is a reliable and efficient choice for many electronic applications.
