Tantalum Capacitors

The M39003/01-7074H capacitor is part of the tantalum capacitor family. The technology of tantalum capacitors has been around since the early 1950s when Bell Telephone Laboratories developed the sintered tantalum process. It is a form of electrolytic capacitor which features a tantalum anode, a dielectric layer, a Ta2O5 dielectric oxide, and a solution-treated, sintered pellet cathode. The anode is covered by a manganese dioxide layer and a cathode lead.Tantalum capacitors provide a number of advantages over other types of capacitors. These include higher energy storage per unit volume, longer life, and higher ripple current capabilities. They are also relatively small and lightweight, making them ideal for use in portable and miniature electronic equipment.The M39003/01-7074H capacitor has a capacitance range of 3.3 µF to 100 µF. It is designed for use in power supplies, instrumentation, and other electrical circuits that require high capacitance values in small package sizes. It is rated for voltages up to 35V and offers medium to low ESR values (<50 mOhm). It has good high-temperature performance, with operating temperatures ranging from -55C to 125C.The main application fields for this type of capacitor are power supplies, dc-to-dc converters, power amplifiers, switching regulators, and other electronic circuits.Tantalum capacitors work on the principle of electrolytic storage of charge. As an electric current is passed through the capacitor, an electric field is created in the dielectric material. This field is proportional to the electric potential, and the amount of electric potential stored is proportional to the capacitance of the device. When the electric field is discharged, it is released, creating an electric current.The M39003/01-7074H capacitor is designed for use in high-temperature environments and offers medium to low ESR values. It is ideally suited for use in power supplies, instrumentation, and other electrical circuits that require high capacitance values in small package sizes.
