The Role and Use of Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitors. They use metal tantalum as a medium, unlike ordinary electrolytic capacitors, which use electrolyte. Unlike ordinary electrolytic capacitors, tantalum capacitors are wound with aluminum-coated capacitor paper. inductance, but this also limits its capacity. In addition, since there is no electrolyte inside the tantalum capacitor, it is very suitable for working at high temperature. Advantages of tantalum capacitors

Tantalum capacitors have excellent performance. They are small in size and can achieve large capacitance among capacitors. There are few competitors in power supply filtering, AC bypass and other applications. Tantalum capacitors have a wide operating temperature range from minus 25 degrees to 125 degrees with a unique process. In addition, they have strong stability, high precision, and small size. The capacitors are reinforced and restored by oxide film dielectrics. Insulation ability, with unique self-healing function, so that it does not suffer from cumulative damage to the connection.

Disadvantages of tantalum capacitors

If there are advantages, there are bound to be disadvantages, which are mainly reflected in the following points. The first thing to say is that the price is high. Tantalum capacitors with the same capacity are ten times more expensive than ceramic capacitors. The second is the small capacity. Since the electrolyte is not used as the medium, the capacity is limited and cannot be very high. Then there is the weak withstand voltage and current capability, and can only be used in some places where the voltage and current are small. Applications of Tantalum Capacitors

Tantalum capacitors have stable performance, high accuracy, and excellent high-frequency filtering. However, due to the high cost of tantalum capacitors, they are generally used in relatively high-end products, such as computer motherboards, graphics cards, or mobile phones. A large amount of tantalum is used Therefore, tantalum capacitors are generally used in circuits that require relatively high stability of capacitors, and are suitable for cutting-edge military, computers, automobiles, communications, high-end household appliances and other fields.
