Introduction to Tantalum - Polymer CapacitorsTantalum - polymer capacitors are composite capacitors that are mainly used in fields such as military, aerospace and other complex electronic applications. They are typically preferred over electrolytic and ceramic capacitors due to their superior physical and electrical characteristics, and the fact that they are the most reliable and cost effective high-density capacitor types, which are highly temperature resistant and have low ESR.T540B226K010AH8710WAFL application field and working principleThe T540B226K010AH8710WAFL is a tantalum-polymer capacitor designed for high-reliability and general-purpose applications in the aerospace and military industries. Its main features include a high-temperature rating of 150°C (which allows it to operate continuously in temperatures as high as 105°C), long service life expectancy due to its useful life of 2000 hours, high capacitance of 47uF, and a wide operating voltage rating starting at 4V up to 10V.The operating principle of this capacitor is based on the electrochemical process, which involves the movement of ions between the anode and the cathode due to the electrical current that passes through the device. The anode is constructed of a porous tantalum material that has been soaked in a solid electrolyte, and the cathode is built from a thin porous layer of semi-conductive material that is also soaked in electrolyte. The capacitor will initially be discharged because when it’s unloaded, its anode/cathode dipoles come together and form a neutral charge. However, when an external voltage is applied, the ions will move from the cathode to the anode, generating an electric charge, which is stored in the form of energy until the capacitor is discharged. The capacitance of the component is determined by the size of the porous material, as well as by the surface area of the cathode and anode. The component also has excellent self-healing properties, which means that when the component is subjected to high voltage, its dielectric properties are automatically restored to their original state. This ensures the component’s high reliability and enables it to withstand high temperatures. Additionally, the component is also highly resistant to reverse voltage, because its construction eliminates potential structural damage that would otherwise be caused by polarity reversal.ConclusionThe T540B226K010AH8710WAFL is a high-performance, end-device-grade, tantalum-polymer capacitor designed for use in extreme environmental conditions that require high-reliability, quality assurance and long service life. Its features make it an ideal component for a wide range of aerospace and military applications, such as communications and navigation systems. Its excellent high-temperature rating, wide voltage rating and self-healing properties make it a reliable and cost-effective solution for high-density applications.
