Tantalum Capacitors

Tantalum capacitors are a type of electronic component that is used in computers and other electronic devices to store electrical energy and as a part of the electrical system. They are made out of an alloy of tantalum and other metals, and are generally used as an alternative to traditional ceramic and film capacitors. Tantalum capacitors are usually available in an axial or radial form, and are spaced between the substrate (circuit board) and the metal layer (trace) on the opposite side of the substrate.

TH3C475M020C1700 application field and working principle

The TH3C475M020C1700 is a high-quality, high-temperature radial-leaded Ta tantalum capacitor. It is constructed with a unique blend of metal and resin materials, allowing for excellent temperature stability and long term reliability in the most extreme environments. It is widely used in automotive, medical, industrial, aerospace, audio, and other high-performance application fields.Tantalum capacitors generally work by storing the electrical charge on one side of the capacitor (the anode), and creating an area of high electrical potential on the other side of the capacitor, or the cathode. The charge builds on the anode until it reaches a maximum capacity. When the current reaches this predetermined level, the capacitor will allow the charge to move through the capacitor, causing a discharge. This process is repeated until the capacitor is fully discharged.

Advantages and Disadvantages

Tantalum capacitors have several advantages, including a higher capacitance-to-volume ratio, and a greater temperature stability range than ceramic and film capacitors. Additionally, they are more resistant to vibration, temperature extremes, and are typically lower in cost than other types of capacitors. On the other hand, tantalum capacitors can suffer from phenomenon known as “voltage derating”, which is when a capacitor’s capacitance is reduced at high voltages. Additionally, if overcharged with too much current, these capacitors can become very hot and potentially catch on fire.

Conclusion

Tantalum capacitors are a great choice for high-performance applications that require a reliable, temperature stable capacitor. The TH3C475M020C1700 is a high quality, radial-leaded Ta tantalum capacitor that is widely used in a variety of applications. While it has several advantages, such as high capacitance-to-volume ratio and temperature stability, it is important to be aware of its potential drawbacks, such as voltage derating and the risk of overcharging.
