Tantalum Capacitors

Tantalum capacitors are small, cylindrical capacitors made out of tantalum that are widely used in a variety of consumer goods including portable computers, cellular phones, camcorders, and digital cameras. These capacitors function in much the same way as other capacitor types, using an electric field to store a charge, but they have a significantly higher capacitance than other types of capacitors, meaning they can store more charge. This makes them ideal for applications requiring high capacitance densities, such as low-power DC-DC converters and microprocessor power supplies.

M39003/01-2758/HSD Application Field and Working Principle

The M39003/01-2758/HSD is a high-end tantalum capacitor manufactured by Vishay, specifically designed for automotive and industrial applications. This tantalum capacitor is designed to meet extremely demanding conditions, such as vibration, shock, and temperature extremes, and is particularly suited for applications requiring low ESR (equivalent series resistance) and high ripple current capabilities. In addition, this series of capacitors is available with conformal coating for maximum protection against environmental influences.

Tantalum capacitors work just like any other capacitor, in that it stores a charge, and then stores energy by releasing that charge. This is done by storing an electric field between the two plates of the capacitor. In the case of the M39003/01-2758/HSD, the two plates are created out of tantalum and an electrolyte material, and the electric field is generated between them, allowing the capacitor to store energy. As current is applied to the capacitor, the electric field between the plates increases, which in turn stores more energy, and allowing the capacitor to operate at a much higher capacitance than comparable capacitors.

The M39003/01-2758/HSD has several advantages that make it ideal for automotive and industrial applications. The most significant advantage is its very low ESR, which helps to reduce electrical circuit noise, as well as its high ripple current capabilities, which help increase the lifetime of the capacitor. In addition to its low ESR and high ripple current capabilities, this series of tantalum capacitors is also designed to withstand shock, vibration, and a wide range of temperatures. This makes them ideal for use in challenging environments, such as automotive and industrial applications.

In conclusion, the M39003/01-2758/HSD is a versatile and reliable tantalum capacitor designed for use in automotive and industrial applications. This capacitor has been designed for maximum protection against environmental influences due to its high ripple current capabilities and its conformal coating, making it extremely reliable for even the most demanding applications. Its low ESR and high ripple current capabilities allow it to store more energy than comparable capacitors, making it ideal for low-power DC-DC converters and microprocessor power supplies.
