T491A104K050AT4801 is one of the most popular products in the Tantalum Capacitor(TC)family. A TC is a type of electrochemical capacitor primarily used in electronics applications. TCs are polarized, have relatively high capacitance values, high equivalent series resistance (ESR), low leakage current, and a wide range of operating temperatures. TCs are generally used for low-voltage and high-current applications, such as in mobile phones, laptops and power supplies.

The T491A104K050AT4801 is an Axial TC specifically designed to address the needs of application in which fast switching, or high frequency is required. This TC features a comparatively small physical size, a high operating temperature, and low ESR, making it preferable for applications where space and efficiency are of great importance. Its theoretical maximum working voltage is 6.3V and its maximum useful temperature is 85 Celcius.

TCs are passive devices which offer capacitive reactance, reducing the availability of a continuing electric current after it has been applied to the capacitor. This type of capacitor functions in the same way as another type of capacitor, the polarized electrolytic capacitor, however, the TC can handle much higher frequencies and temperatures compared to the latter.

The electrodes of a TC are made of tantalum and are made of manganese dioxide material. This material is the electrolyte and allows electrons to flow between the two electrolytes and the capacitor dielectric. This provides a larger capacitance value and low ESR. Additionally, due to the low ESR, there is less power dissipation and lower heat build-up in the capacitor, making the TC ideal for high frequency and power circuits.

The T491A104K050AT4801 TC is typically used in numerous applications, including DC-DC converters, mobile audio amps, power supplies, secondary lithium batteries, and laptop computers. The low and stable ESR, high frequency stability, and large capacitance of this TC makes it ideally suited for these types of applications, as well as almost any kind of power and high frequency application, including TV Power Supply, Solar Inverters, Battery Supplies, and various Industrial Automation Products.

In conclusion, the T491A104K050AT4801 TC is a highly reliable, high-performance and energy-efficient capacitive solution for many electronic applications. Its low ESR value and high frequency stability makes it extremely suitable for high-frequency applications, while its high capacitance values enable it to store a large amount of energy. Its small size, high working temperature and low leakage current are also ideal, making it a highly sought-after product within the TC family.
