Tantalum - Polymer Capacitors

T540D477M003BH8505 are high-performing, lightweight, and cost-effective tantalum-polymer capacitors used in advanced electronics across a broad range of application fields. Due to their superior qualities, they have gained popularity among industrial and consumer-level electronics in a wide variety of applications, such as advanced military, aerospace, automotive, medical, data storage/processing, and portable device markets.

Application Field

T540D477M003BH8505 are a type of surface-mount chip capacitor. Popular in military, aerospace, and automotive markets, they offer a number of advantages to engineers and designers. Due to their very low resistance, these capacitors are particularly suitable for high-frequency applications and are excellent for switching regulator applications and decoupling. They are commonly used in computers, computer motherboards, base station radios, military guidance systems, cell phones, and many other electronic products.

T540D477M003BH8505 can also be used as high-surge and high-current dampers. In addition to their common industrial applications, they can also be beneficial when used in consumer items such as cell phones and tablets, as well as many other mobile, personal electronic devices. These capacitors are also increasingly being used in robotics and other IoT (Internet of Things) applications.

Working Principle

T540D477M003BH8505 capacitors are comprised of a conductive polymer that is sandwiched between two solid electrolytic plates. This structure creates a strong, reliable, and temperature-stable connection. The polymer used in these capacitors exhibits highly conductive properties without the use of complex electrolytes. This means that the capacitance is highly stable and the ability to withstand voltage is maximized.

The printed circuit board (PCB) of the capacitor is built in a series-parallel configuration and coated with a conformal layer, which prevents degradation of the internal components and enhances their reliability. This configuration also helps to equalize stresses between the two electrodes, thus increasing their longevity. The capacitors are also pre-conditioned prior to installation, meaning that they are already resistant to environmental stresses and temperature changes.

T540D477M003BH8505 capacitors provide excellent electrical conductivity, low ESR (equivalent series resistance), minimal electrical instability, superior high-temperature performance, and increased power reliability. This makes them ideal for applications that require high levels of accuracy and performance. In addition, these capacitors have excellent current handling capabilities and are available in a wide range of capacities, voltage ratings, and package sizes.

Conclusion

T540D477M003BH8505 are cost-effective, high-performance, lightweight, and reliable tantalum-polymer capacitors that are becoming increasingly popular in industrial and consumer-level electronics. The combination of the polymer sandwiched between two solid electrolytic plates and the pre-conditioning process that they undergo ensures an even, reliable, and long-lasting connection. Additionally, their excellent electrical conductivity, low ESR, proportionate voltage ratings, and increased power reliability make them ideal for applications which require constant, accurate performance.
