Tantalum – polymer capacitors have become an integral part of modern electronic circuits. They are increasingly used as an ideal replacement for traditional electrolytic capacitors, due to their sustained reliability, low ESR, high capacitance density, low cost and long life cycle. The 4TPE470MCL is one such capacitor, and its application field and working principle are described below.

The 4TPE470MCL is a high-temperature tantalum – polymer capacitor. It is generally used for applications at extreme temperatures ranging from -55°C up to 125°C, and is suitable for high frequency and power circuits such as power supplies and servers. This capacitor also features very low ESR at high frequencies, making it suitable for high capacitance density applications such as in high-end laptops, mobile phone screens and UHD TVs. Its significant characteristics include a capacitance up to 4.7µF and a voltage rating of 10V at 25°C, with a lower voltage rating at higher temperatures.

The 4TPE470MCL is made up of a sintered tantalum anode, a manganese dioxide (MnO2) cathode and a solid polymer electrolyte between them. Its working principle is based on Faraday’s law of capacitor charging and discharging, which states that a capacitor stores charge when a voltage is applied to its plates, and releasing it when the voltage is reduced. In this kind of capacitor, the anode is coated with an electrically conductive oxide layer made of MnO2, which acts as an electrolyte to store and release the charge. When a voltage is applied to the capacitor, electrons flow from the anode to the cathode, and an electric field is created between the plates. When the voltage is reduced, the electrons are drawn back to the anode, and the electric field is reversed. This causes the dielectric material between the plates to become polarized and form an electrical charge.

The 4TPE470MCL has a long life cycle, and its performance is not affected by high temperatures. It is a reliable and cost-effective solution for high-temperature applications, and is increasingly being used in a wide range of applications, such as power converters and HVAC systems. This capacitor offers a wide variety of advantages, including high reliability, low cost, and high capacitance density, making it an ideal replacement for traditional electrolytic capacitors.

The 4TPE470MCL is a reliable and durable capacitor, and it provides excellent performance in high temperature applications. Its working principle is based on Faraday’s law of capacitor charging and discharging, and its high capacitance density makes it suitable for high-end laptop and other power circuitry. This capacitor is widely used in a variety of industries, including HVAC and power converters, and is an ideal alternative to traditional electrolytic capacitors.
