Tantalum Capacitors

Tantalum capacitors, otherwise known as tantalum electrolytic capacitors, are solid electrolyte capacitors that use a tantalum anode and covered by a dielectric oxide layer as the anodic active material. They feature stable performance, low leakage currents and low ESR values, as well as a large capacitance density in a small package. Applications for tantalum capacitors include consumer electronics, industrial control, automotive and military electronics, computers, aerospace and telecommunication.

T494A156M010AT

The T494A156M010AT is an example of a tantalum capacitor. It has a maximum capacitance of 156 uF and a maximum working voltage up to 10V, making it suitable for use as a primary energy storage device in consumer, computer and industrial electronics.

Application field

T494A156M010AT tantalum capacitors are primarily used in consumer electronics, including televisions, DVD players and other audio-visual equipment. They are also suitable for use as a hold-up device for computer power supplies and in industrial control applications. In these applications, the capacitor stores energy until it is needed, thus improving power efficiency and performance.

Working Principle

Tantalum capacitors work on the same principle as other types of electrolytic capacitors. An electric current is passed through a pair of electrodes to form an electrolytic oxide layer on the anode surface. This oxide layer acts as a dielectric, and acts as insulator between the anode and the cathode. A voltage applied across the electrodes causes ions to be attracted, creating an electrostatic field. This field stores electrical energy as electrostatic charge on the capacitor.

The T494A156M010AT capacitor has a 10V maximum working voltage, which means that the electrostatic field needs to have a minimum strength of 10V in order for the capacitor to work properly. When the voltage applied to the capacitor exceeds the maximum voltage, the electrostatic field weakens and the capacitor will no longer be able to store electrical energy.
