Tantalum-polymer capacitors are a type of energy storage device found in many electronic products, from mobile phones and laptops to medical devices and home appliances. The T540D227K004CH86057280 is a standard model from a leading manufactorer and is designed to be used in a wide range of applications. This article will explain the application field and working principle of the T540D227K004CH86057280.

Application Field of T540D227K004CH86057280

The T540D227K004CH86057280 is a Radial Lead, dipped style capacitor. It is typically used in mobile phones, laptops, and other portable devices, as well as in medical devices and home appliances. The capacitor is designed to be shock-resistant and is well-suited for use in vibration-prone applications such as automotive or aerospace electronics. It is also suited for high temperature use, with a rating of up to 125 degrees Celsius. The capacitor is available in a range of capacitance values from 1µF to 100µF, with voltage ratings from 6.3V to 150V.

Working Principle of T540D227K004CH86057280

Tantalum-polymer capacitors use a solid electrolyte of tantalum salts and a polymer separator Film. When a voltage is applied to the capacitor, a current flows through the film, which transfers ions to the other plate of the capacitor. The transfer of ions creates an electric field across the film, allowing the capacitor to store an electrical charge. This electric field is maintained even when the voltage applied to the capacitor is removed, allowing the capacitor to hold a charge. This makes tantalum-polymer capacitors valuable for storing power in areas with fluctuating power supplies.

The T540D227K004CH86057280 uses a design that maximizes energy storage, with a high energy density per volume. This is achieved by using a thinner Electrolyte Film, which reduces the size of the capacitor while improving performance. It also has a low Equivalent Series Resistance (ESR), which improves its ability to supply power in high-frequency or switch-mode applications. Additionally, the capacitor is designed to be highly reliable, with an exceptionally low failure rate.

Conclusion

The T540D227K004CH86057280 is a Radial Lead, dipped style capacitor offering a wide range of applications. It is mainly used in mobile phones, laptops, and other portable devices, as well as in medical devices and appliances. The capacitor has a high energy density and low ESR, making it ideal for high-frequency or switch-mode applications, as well as for storing power in areas with fluctuating power supplies. It is also designed to be shock-resistant and is well-suited for use in vibration-prone applications. The capacitor has a rating of up to 125 degrees Celsius and is available in a range of capacitance values and voltage ratings.
