Tantalum capacitors are capacitors that use tantalum as the dielectric electrochemically formed into a porous layer. The exciting properties of tantalum, combined with its affordability and high capacitance guarantee that it is a popular choice, widely used in applications like digital and mobile devices. One of the most popular models within the family is the M39003/09-0163 capacitor.The M39003/09-0163 has a capacitance range from 0.001 µF to 0.1 µF and a working voltage of 10 volts. This capacitor utilizes tantalum for its dielectric, which effectively makes them have a lower ESR compared to traditional aluminum electrolytic capacitors. The M39003/09-0163\'s advantages include: it is temperature stable, has a long life span, and can operate at higher temperatures than some other capacitors. This capacitor is also popular for its size - it is small but still has a large values of capacitance. Due to its advantages over other capacitors, the M39003/09-0163 is mainly used in applications like military circuitry, consumer electronics, computers, and medical devices.The working principle of the M39003/09-0163 is the same as for other tantalum capacitors. The capacitance of the M39003/09-0163 is created by forming a thin, porous dielectric layer on the surface of the tantalum anode. This layer, combined with the electrolyte solution which serves as the dielectric material between the anode and the cathode, creates the capacitor’s effective capacitance.The M39003/09-0163 capacitor has two important points of failure. The first point of failure is the anode-cathode interface which can be prone to short-circuits. The second point of failure is the tantalum layer itself, which can suffer from oxidation or crystallization due to temperature changes. To prevent these failure points, the M39003/09-0163 features a low ESRCapacitor element, an internal shield, and a fully sealed case.In conclusion, the M39003/09-0163 capacitor is a highly specialized capacitor that offers a wide range of advantages. With its high capacitance values to small size and its low susceptibility to short-circuits, the M39003/09-0163 is an excellent choice for applications like military circuitry, consumer electronics, computers, and medical devices.
