Tantalum capacitors, commonly referred to as TaCaps, consist of a dielectric layer of tantalum pentoxide, sandwiched between two electrode layers of tantalum metal. The TAJE687K002RNJ is a popular capacitor of this type, and it is used in many applications. In this article, we will discuss the application field and working principle of the TAJE687K002RNJ.

The TAJE687K002RNJ is a non-polarised, axial-leaded, surface-mount capacitors. It is available in sizes ranging from 0603 to 2225, and with capacitance values ranging from 1pF to 680nF. It has a voltage rating of 6.3V and a temperature range of -55C to +125C.

The TAJE687K002RNJ is suitable for use in many applications, including power supplies, data processing, communications, and automotive systems. Its high ripple current capabilities make it ideal for filtering applications, such as power supplies and audio circuits. Its low ESR (equivalent series resistance) and ESL (equivalent series inductance) also make it suitable for frequency-sensitive applications. Its high-temperature rating makes it suitable for high-temperature environments, such as engine compartments and military systems.

The working principle of the TAJE687K002RNJ is based on the knowledge that electricity can be stored in a capacitor, and the capacitor can be used to filter and smooth out signal noise in an electrical circuit. In a TAJE687K002RNJ, electricity is stored in the dielectric material, which is sandwiched between two tantalum-metal electrodes. The tantalum-metal electrodes allow electricity to move between them, while the tantalum pentoxide dielectric material prevents it from moving between the two electrodes.

When current flows through the capacitor, the amount of charged particles in the dielectric layer will increase, which stores energy in the form of electrostatic charges. Depending on the size of the capacitor, this energy is released through the leads of the capacitor at a controlled rate. This creates a smooth DC output, which is used in applications such as power supplies, audio circuits, and automotive systems.

In conclusion, the TAJE687K002RNJ is a popular tantalum capacitor, which is suitable for many applications, from filtering and smoothing out signal noise, to providing a DC output. Its high ripple current capabilities, low ESR and ESL, and high-temperature rating make it ideal for a wide range of applications. Knowing the working principle of the capacitor is also essential in order to safely and efficiently use it in an electrical circuit.
