T491C685M020AT4153

T491C685M020AT4153 are tantalum capacitors, which are used in a wide range of applications. Tantalum capacitors are small, cylindrical devices made of a tantalum powder and other metals, such as manganese dioxide, that are encased in a metal case. Tantalum capacitors are used in a variety of applications, including power supplies, computers and other digital devices, automotive electronics, LED lighting systems, and more.

A key characteristic of tantalum capacitors is their extremely high capacitance-to-volume (CV) ratio. This makes them an ideal choice for applications that require a large amount of capacitance in a small package. This is especially important in designs where space is a premium, such as in portable devices or in dense circuit boards.

The working principle of a tantalum capacitor is fairly simple and follows the same operating principles of all capacitors. To charge a capacitor, a voltage source is connected to it and electrons are attracted to the plate of the capacitor. When the desired voltage is reached, the electrons are prevented from flowing and the capacitor is said to be “charged”. The number of electrons drawn to the plate of the capacitor depends on the surface area of the plate, the type of material the plate is made from, and the voltage applied to the capacitor. The total amount of stored energy in the capacitor is determined by the amount of surface area of the plate, the type of material the plate is made from, and the voltage applied to the capacitor. This stored energy can then be quickly released when the capacitor is connected to another circuit in order to supply a quick burst of energy.

T491C685M020AT4153 are high-performance, low-profile tantalum capacitors with a rated voltage of 20V and a capacitance of 85μF. They are typically used in applications such as power supplies, computers and other digital devices, automotive electronics, and LED lighting systems. The rated voltage of the T491C685M020AT4153 is 20V, meaning they are much better suited for higher voltage applications than standard electrolytic capacitors. The 85μF value is also higher than most standard electrolytic capacitors, making them more efficient and allowing them to handle more current.

T491C685M020AT4153 can also be used in low-power applications as its low-profile makes them well suited for mounting in confined spaces. They are also extremely reliable and are expected to have a long life of up to 10 years. They are typically soldered to PCBs and then protected with conformal coating to prevent any moisture or dust from damaging them.

In conclusion, T491C685M020AT4153 are high-performance, low-profile tantalum capacitors with a rated voltage of 20V and a capacitance of 85μF. They are suited for a wide variety of applications, including power supplies, computers and other digital devices, automotive electronics, and LED lighting systems. They are highly reliable, have an expected life of up to 10 years, and their small size makes them well suited for mounting in confined spaces. Overall, T491C685M020AT4153 are an excellent choice for both high- and low-voltage applications that require a small, reliable capacitor.
