Tantalum Capacitors

T491C685K035AT4838 is a type of electronic component, also known as a tantalum capacitor. They are generally used in digital circuits to store electrical charge, allowing the stored energy to be released when needed.

Application Field

T491C685K035AT4838 might be used in digital circuits for computers, mobile phones, consumer electronics and industrial equipment, as a replacement for an electrolytic capacitor. Such components are usually found in consumer electronic devices and electronic control panels, and digital circuits are rarely found without some type of capacitor in order to provide energy storage and to ensure proper circuit operation.

T491C685K035AT4838 also has the ability to hold a charge for minutes or even hours, making them suitable for applications that require slow release of energy. Such applications can range from applications that require pulses of electrical energy (such as motor starters and sensors) to those requiring sustained output such as audio amplifiers and rechargable batteries.

Working Principle

T491C685K035AT4838 tantalum capacitors are designed for storing electrical charge. This charge is stored on a thin dielectric material, usually aluminum oxide. The dielectric material is between two conductive plates, which create an electric field. The charge is stored on the dielectric material, and can be released when required.

The capacitance of the T491C685K035AT4838 is determined by the size and shape of the dielectric material, as well as the distance between the two conductive plates. Higher capacitance is achieved by increasing the size of the dielectric material, decreasing the distance between the plates and using a material with a higher dielectric constant.

T491C685K035AT4838 are polarized capacitors, meaning they have a positive and a negative terminal. The difference in these terminals determines which side the charge flows. When the voltage is applied to the positive terminal, the negative terminal will build up with electrons while the positive terminal builds up with protons. When the voltage is reversed, the charge will flow the opposite direction, with the negative terminal filling up with protons and the positive terminal filling up with electrons.

Conclusion

T491C685K035AT4838 is a type of tantalum capacitor that is used for digital circuitry, ranging from consumer electronics to industrial applications. These capacitors are designed for storing electrical charge and provide a slow release of energy when needed. The capacitance of these capacitors is determined by size, distance between conductive plates and dielectric material. They are also polarized, meaning there are a positive and a negative terminal that determine the flow of charge.
