T491B225K035AT48607622 is a series of tantalum capacitors available in a wide range of capacitance and voltage ratings, making it suitable for a variety of applications. It contains two main parts – a tantalum anode and a manganese dioxide cathode – sealed away in a hermetically sealed ceramic or metal case. It is known for its long life, low internal resistance, and excellent stability.
Application Field of T491B225K035AT48607622
T491B225K035AT48607622 is widely used in consumer electronics, industrial, and automotive markets due to its high peak current capabilities, high reliability, and wide temperature range. Its high capacitance density and low ESR makes it a popular choice for pulse and bypass capacitors in industrial switch mode power supplies and decoupling applications. Tantalum capacitors also offer a small case size which is suitable for high-density printed circuit layouts.
It is also used in small signal gate and base-drive circuits, as well as for snubbers in high-frequency circuits. Tantalum capacitors are also used in high-frequency power supplies, filters, and PLL systems, as well as for suppressing EMI in communication systems. In addition, its high volumetric efficiency allows for a low component count for the same capacitance value, making it a good choice for high-voltage DC-DC converters.
Working Principle of T491B225K035AT48607622
T491B225K035AT48607622, like all other tantalum capacitors, works on the principle of dielectric absorption. The anode, which is the main conducting element, is the source of the charge, while the cathode, made of manganese dioxide, is the sink. When the capacitor is connected to a power source, electrons are transferred from the anode to the cathode, forming an electric field on the boundary between the two layers of materials. This electric field stores the energy and opposes any further voltage increases.
The cathode layer allows the electrons to diffuse back and forth within the capacitor, increasing its charge and allowing the capacitor to store more energy. When the capacitor is then disconnected from the power source, the charge remains stored in the capacitor and it can be used for other applications. This principle of dielectric absorption is what makes tantalum capacitors so reliable, and their long life makes them a popular choice for many applications.
Conclusion
T491B225K035AT48607622 belongs to the family of tantalum capacitors. This capacitor is widely used in consumer electronics, industrial and automotive markets due to its high peak current capabilities, high reliability and wide temperature range. Its high capacitance density and low ESR makes it a popular choice for pulse and bypass capacitors in industrial switch mode power supplies and decoupling applications. The capacitor works using the principle of dielectric absorption, which makes it a reliable and long lasting component suitable for many applications.
