Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitors, which are capacitors that store energy by means of two thin solid layers of metal that are separated by a thin layer of insulating material called the dielectric. They are ideally suited for applications with high power densities and precise frequency responses, due to their small size and low profile. The T491A104M035AT2478 is a type of tantalum capacitor that has a maximum thermal resistance of 4.1°C/W, meaning it can dissipate heat more effectively than other tantalum capacitors.

T491A104M035AT2478 Application Field

The T491A104M035AT2478 is a fairly small and low profile tantalum capacitor, making it ideal for applications where space is at a premium, such as in consumer electronics products. It also has excellent frequency response characteristics, with a range of DC to 20kHz and a Q factor of 3, making it suitable for use in power supplies, radio systems and primarily audio systems. Additionally, its high temperature endurance makes it useful for automotive applications, such as controlling combustion.

T491A104M035AT2478 Working Principle

The capacitor works by using two plates, with one positively charged and one negatively charged. This creates an electrostatic field between the two plates, and when a voltage is applied across the plates this field causes a charge to build up on the two plates. This charge leads to electrons being attracted to the negatively charged plate, and protons to the positively charged plate. As a result, the two plates are held together by a new bond created by the electrons and protons, called an electrostatic bond, which then stores energy. When the voltage applied across the plates is removed, the electrons and protons move back to their original positions and the electrostatic bond is broken, releasing the stored energy.

Conclusion

The T491A104M035AT2478 is a small and low profile tantalum capacitor, with excellent frequency response characteristics and high thermal resistance, making it ideal for applications such as consumer electronics products, radio systems, audio systems and automotive applications. It works by using two plates to create an electrostatic field, when a voltage is applied this field causes charge to build up on the two plates and holds them together in an electrostatic bond, which then stores energy. When the voltage is removed the stored energy is released.
