109D277X9050T2

Tantalum capacitors have become a common choice for several different applications due to their small size, high energy efficiency, and superior reliability. The specific 109D277X9050T2 tantalum capacitor is a surface mount device designed for applications such as high frequency bypass, filter, and coupling applications. This particular device offers a particularly high voltage rating, low parasitic inductance, and wide operational temperature range. It is well suited for applications in industrial, automotive, and aviation electronics.

Working Principle

Tantalum capacitors work on the same principles as other capacitors: they store energy and then release it gradually when current is applied. The electric field between the positive and negative plates of the capacitor is the force that stores the energy. The difference between tantalum capacitors and their other counterparts is the dielectric. Tantalum capacitors are made with tantalum oxide, which has a much higher electric flux density than other dielectrics. This allows for smaller physical sizes and higher capacitance values.

Features

The 109D277X9050T2 tantalum capacitor is a surface-mount device, with a size of 0.37” x 0.26” x 0.2”. It offers low impedance and high capacitance values, a wide temperature range of -55ºC to +125ºC, and a range of capacitance values from 0.0047 μF to 270 μF. It has a rated working voltage of 27V (DC) which can be increased up to 50V with a voltage coefficient of 1.0 V/V.

Uses

Tantalum capacitors are used in a variety of applications, including power-supply inputs and outputs, filtering, snubbing, and bypassing. They are popular due to their small size and superior performance characteristics, including high ripple current capabilities, excellent voltage regulation, and long-term reliability. The 109D277X9050T2 is well suited for applications such as high frequency bypass, filter, and coupling applications in industrial, automotive, and aviation electronics.

Conclusion

The 109D277X9050T2 tantalum capacitor offers superior performance characteristics, excellent voltage regulation, and long-term reliability. It is a popular choice for industrial, automotive, and aviation electronics applications, due to its compact size, low impedance, and wide range of capacitance values.
