Tantalum Capacitors: M39003/03-0227/TR Application Field And Working PrincipleTantalum capacitors are one type of capacitor that provides values of capacitance typically from 1 to 10µF in packages sizes ranging from 0201 to D and are suitable for use in a wide range of applications. Among the applications they are used in include microprocessors, microcontrollers, and memory chips in consumer electronics, medical, military, and industrial markets. The M39003/03-0227/TR tantalum capacitor, for example, is perhaps one of the most popular types of tantalum capacitors and is used in many types of electrical applications as it is designed to withstand a wide temperature range, from -55°C to 125°C. Specifically, it is used in military aircraft and aerospace applications. It is a radial lead tantalum capacitor with a voltage rating of 26V and a capacitance of 1.2μF. The M39003/03-0227/TR is also available with a reverse voltage of 13V, but its capacitance range is still subject to the same voltage limit.Tantalum capacitors are comprised of the anode (negative element), a cathode (positive element) and a dielectric (the element that stores energy). The base material is a combination of tantalum powder and a manganese dioxide (MnO2) powder, which is pressed into the desired shape and size. The anode is usually bare metal while the cathode consists of either a manganese dioxide powder or an electrolytic, depending on how the capacitor is constructed.The working principle of a tantalum capacitor is similar to that of any other capacitor. When a voltage is applied to the capacitor, the dielectric layer expands and creates a barrier between the anode and cathode. This barrier resists the flow of electrons, which allows energy storage within the capacitor. This stored energy can then be used during periods of high current demand.The M39003/03-0227/TR, for example, is a radial lead thermally stable low-leakage tantalum capacitor where the electrolyte is solid MnO2 held under pressure with dielectric layer formed by the solid electrolyte. It provides short-term electrical stability with very low leakage, making it ideal for high-current, high-temperature applications. The capacitor also features gold-plated pins for surface mount applications and a silicone-based adhesive that allows for easy soldering.Tantalum capacitors are widely available in a variety of formats, and the M39003/03-0227/TR is one of the most popular ones on the market today. Its unique properties give it an edge over other types of capacitors in terms of performance. In addition, it is relatively inexpensive and easy to assemble, making it not only a great choice for military and aerospace applications but also for a variety of other applications.
