Tantalum - Polymer Capacitors

Tantalum - Polymer capacitors are widely used in the electronics industry due to their advantages over traditional aluminum electrolytic capacitors. A prime example of the versatility of tantalum-polymer capacitors is the T55B107M6R3C0040 . This capacitor is a surface mount, Class 2 device designed for repetitive peak pulse current handling up to 5A for 4 seconds without derating. It is also capable of handling continuos currents of up to 2A. In addition to its impressive current handling capabilities, it also has an exceptionally low ESR (Equivalent Series Resistance) of 0.009Ω at 100kHz. It offers a wide range of voltage values ranging from 6V - 10V or 6.3V - 16V, and a temperature range of -55°C to +125°C.

Applications

The T55B107M6R3C0040 is used primarily in miniaturized circuit designs such as in smartphones, computers, and many other electrical devices. Its low ESR combined with its high peak pulse current make it ideal for use in a wide range of power supplies and AC/DC converters. It is also useful in solenoid drivers, motor control circuits and high-frequency switching circuits. In high-temperature operations, such as those encountered in computer and automotive systems, it can be used as signal line filters. Its acoustic noise immunity also makes it suitable for use in audio power applications.

Working Principle

The T55B107M6R3C0040 is built using a tantalum anode and solid manganese dioxide cathode. A special polymer film, known as polypropylene, is used to separate the two and forms the dielectric. The polypropylene film forms a dielectric which is thin and conforms to the contours of the anode. The thin polypropylene dielectric lowers the equivalent series resistance (ESR) and increases capacitance, allowing for an increase in current flow and voltage withstanding capability. Unlike aluminum electrolytic capacitors, tantalum-polymer capacitors have no liquid electrolyte, making them much more reliable and durable in extreme temperatures.

Conclusion

The T55B107M6R3C0040 is an exceptional example of a tantalum-polymer capacitor and is used in a wide range of electronic devices. Its low ESR, high peak pulse current, wide voltage range and temperature range make it ideal for use in many applications. Its non-reactive nature, construction and careful selection of rated parameters make it one of the most reliable and durable capacitors available on the market. As a result, it is growing in popularity and use in all types of electronic circuits.
