Introduction to Tantalum Capacitors

A tantalum capacitor is the generic term for a device consisting of two conductive plates separated by a dielectric material. They are available in different varieties and sizes, depending on the specific application they’re used for. Tantalum capacitors can also be referred to as tantalum electrolytic capacitors, tantalum electrolytes, or simply tantalum. The 298D475X0004K2T is a tantalum capacitor with a specific type of configuration.

298D475X0004K2T Configuration

The 298D475X0004K2T is a surface mount capacitor with 4 terminal pins. It is made from tantalum, with an anodic oxide coating on the surface. The total package size of the capacitor is 4.75mm by 3mm, with a thickness of 0.85mm. The capacitor features a cathode-anode terminal pin configuration, with the negative terminal being the first one along the surface.

Application

Tantalum capacitors are typically used in two main applications: they are used to filter out unwanted frequencies, and they are used to store electrical energy. The 298D475X0004K2T capacitor is a small, compact device that is ideal for use in portable electronics due to its size. It is commonly used in mobile phones, laptops and other electronic devices that require power optimization. It is also suitable for use in digital circuits where electrical resistance is a factor.

Working Principle

The working principle of a tantalum capacitor is based on the Faraday’s law of electrolysis. According to this law, an electrical field is created between two conductive surfaces when an electric current passes through them. The field created by the electric current is used to both store electrical energy and filter out unwanted signals.The 298D475X0004K2T capacitor utilizes the Faraday’s law of electrolysis by using two conductive plates with a dielectric material in between. The conductive plates are then connected to the controlling circuits, where the electric current passes through them. When the electric current passes through the capacitor, an electric field is created between the two plates. This electric field is used to store electrical energy, and also to filter out any unwanted signals that may interfere with the functioning of the circuit.

Conclusion

The 298D475X0004K2T tantalum capacitor is a small, compact device that is ideal for use in portable electronics due to its size. Its anodic oxide coating makes it a good choice for power optimization circuits, as it is resistant to electrical resistance. The device uses Faraday’s law of electrolysis to store electrical energy and filter out unwanted signals, making it a reliable and stable component for most applications.
