Tantalum Capacitors

Tantalum capacitors are devices used to store and release electrical energy. Commonly referred to as ‘tantalum caps’, these capacitors have a unique structure that makes them well-suited for use in difficult, high-temperature and high-humidity environments, making them frequently used in the production of consumer electronics, military and aerospace applications. A specific type of tantalum capacitor is the TH3B475M025D2800.

TH3B475M025D2800 Application Field

The TH3B475M025D2800 is a radial surface mount tantalum capacitor. It has an industry-standard 4-LEAD case, which makes it suitable for space-constrained applications. It is also rated for full-operating temperatures up to 125°C, making it appropriate for use in high-temperature applications. Perhaps its greatest feature is its ability to tolerate extreme humidity levels, even up to 95%, adding to its utility in various industries.

The TH3B475M025D2800 is most often used in loudspeaker circuits, due to its low-equivalent series inductance and low noise production. It is also sometimes employed in medical applications and portable electronic devices, such as digital cameras and electronic gaming systems. Other typical uses for the TH3B475M025D2800 include power supply, RF communication, cellular phones, and audio equipment.

TH3B475M025D2800 Working Principle

The working principle of the TH3B475M025D2800 is based on the capacitor effect, which can cause a voltage to be stored between two conducting plates with an insulating material between them. The charge stored in the capacitor can be discharged when connected with an external circuit. A tantalum capacitor is a specific type of capacitor that uses a tantalum electrolytic cell, which is composed of a tantalum anode, an electrolyte (usually an aqueous solution of potassium hydroxide or a solid tantalum oxide film), and a carbon-based cathode. The cells are packed in a metal envelope and are normally used with a wet electrolyte.

The TH3B475M025D2800 works through the same capacitance principles as other capacitors. It includes an anode and a cathode, where the anode is the positive (+) terminal, and the cathode is the negative (-) terminal. The anode is made of tantalum, and the cathode is a conductive element, such as carbon. When the capacitor is in a circuit, a voltage applied across the anode and the cathode separates electrons at the anode and stores them at the cathode. When the circuit the tantalum cap is connected to is opened, the capacitor slowly releases the charge stored at the cathode.

Conclusion

The TH3B475M025D2800 is a type of tantalum capacitor. It has many features that make it particularly suitable for use in high-temperature and high-humidity environments and for employment in space-constrained applications. It is used in many industries and applications, including portable electronic devices, speaker circuits, power supply, and RF communication. The working principle of the TH3B475M025D2800 is the same as any other capacitor. It stores charge between an anode made of tantalum and a conductive cathode, with the rate of release depending on the circuit it is connected to.
