Tantalum-Polymer CapacitorsTantalum-polymer capacitors are capacitors containing tantalum, cathode material, and polymer material as electrolyte. These capacitors combine the low leakage and high frequency characteristics of a tantalum capacitor with the high temperature performance of a polymer capacitor. The combination of these materials has enabled the manufacture of high-performance, stable, and reliable capacitors. The 4TPH68MHA series is a polymer-tantalum capacitors with a maximum capacitance of 6.8µF and an operating voltage of 10V. It is a surface mount technology (SMT) device, suitable for soldering directly onto a printed circuit board. The 4TPH68MHA series is characterized by its high volumetric efficiency and reliable long-term stability. Application fields of 4TPH68MHA The 4TPH68MHA is suitable for various applications, such as, portable consumer electronics, industrial equipment, aerospace, automotive, and audio/video equipment. It is mainly used as a filtering and decoupling capacitor in DC-DC converters and is also suited for use in switching power supplies, motor drive circuits, and other power applications. Working Principles Tantalum-polymer capacitors work by storing electrical charge between two conducting electrodes in an electrolyte solution. The electrolyte solution provides a conducting medium between the two electrodes which can hold a charge. When an electric field is applied, electrons transfer from one electrode to the other, and this charge is stored in the electrolyte solution. This stored charge can then be used for various applications. The 4TPH68MHA series is constructed of a tantalum anode, tantalum cathode, and a polymer electrolyte. The polymer electrolyte is the main component, providing good insulation and a reliable electric field for storing charge. The tantalum anode and cathode are then used as the conduits for the electrons, allowing for quick and efficient charging and discharging. ConclusionThe 4TPH68MHA series of tantalum-polymer capacitors are high-performance, reliable, and stable capacitors designed for use in portable consumer electronics, industrial equipment, aerospace, automotive, and audio/video equipment. The combination of the tantalum anode and cathode with the polymer electrolyte allows for quick and efficient charge and discharge, making it suitable for use in DC-DC converters and other power applications. It is characterized by its high volumetric efficiency and reliable long-term stability, making it a reliable and efficient choice for a variety of applications.
