Tantalum Capacitors

Tantalum capacitors, also known as Ta2O5 capacitors, are solid electrolytic capacitors composed of tantalum pentoxide film and anodes in the form of sintered pellets. These components are available in a variety of different shapes, sizes, values and voltage ratings. The tantalum capacitor stands out as a component that provides a high temperature, low leakage performance while maintaining a relatively small size.

The M39003/01-6373H tantalum capacitor is a radial leaded chip capacitor with an operating temperature range of -55°C to 85°C and a capacitance range of 10 to 220uF. It is designed for military, aerospace, medical and telecommunications applications. It features a polypropylene dielectric, an ultrasonically welded nickel-barrier termination, and a flexible epoxy snug fit handling.

Applications

The M39003/01-6373H tantalum capacitor is typically used in circuits that need a high stable capacitance in addition to extended life under high temperature conditions. Common applications include energy storage, snubber circuits, DC-DC converters, high frequency converters, and capacitive discharge ignition systems.

The M39003/01-6373H is a popular choice for military and aerospace applications. Their high temperature, shock and vibration ratings, low leakage current, and ability to withstand extreme environmental conditions, make them suitable for use in aircraft, missiles, spacecraft, and other high stress and high altitude uses.

High temperature and shock resistance make it a suitable choice for applications such as defibrillators, MRI systems, ECG detectors, and various other medical electronic instruments.

Working Principle

The M39003/01-6373H utilizes a tantalum metal anode that is surrounded by a tantalum pentoxide (Ta2O5) dielectric barrier. When an electrical current is applied to the device, electrons are drawn to the anode, which ionizes the dielectric barrier and produces an electric field. This electric field creates a capacitance between the two electrodes, which can then be used in a variety of applications.

The M39003/01-6373H tantalum capacitor has the advantage of being able to maintain a high capacitance in a wide range of temperatures. This is due to the crystal structure of the tantalum pentoxide dielectric barrier, which is extremely stable over a wide range of temperatures, and allows for a high capacitance output under these adverse conditions.

The M39003/01-6373H also offers low ESR (equivalent series resistance), which makes it more efficient and reliable than other types of capacitors. This is due to the high dielectric constant of the tantalum pentoxide film, and the geometry of the electrodes which form a low-resistance path between the anode and the cathode.

Conclusion

In conclusion, the M39003/01-6373H is an ideal choice for high-temperature and high-stress applications. Its small form factor and high capacitance output make it well-suited for a variety of military, aerospace, medical, and telecommunications applications. The low ESR and wide temperature range of the device further enhance its reliability and performance. The unique structure of the tantalum capacitor allows it to offer a higher performance than other types of capacitors, making the M39003/01-6373H an ideal choice for extreme conditions.
