Tantalum capacitors are small electronic components used to store and supply electrical energy. A common type is the M39003 / 01-5363H, which is used in both commercial and military applications. This article explores the application and working principles of this type of capacitor.

Features

The M39003 / 01-5363H is an epoxy-coated, hermetically sealed, axial lead tantalum capacitor. It is available in several different sizes, ranging from 0.68μF to 4000μF. The operating temperature range is -55°C to +125°C. The voltage rating is 10V to 50V. The load life rating is at 85°C for 500 hours. It has a capacitance tolerance of ± 10% and a dissipation factor of 0.05 at 1 kHz and 25°C.

Applications

The M39003 / 01-5363H is mainly used in DC-DC converters, switching power supplies, and low impedance filtering applications. It is also used in automotive applications as well as military and aerospace applications. It is used in inverters and radiation-hardened applications due to its proven high reliability.

Working Principle

Tantalum capacitors work by storing alternating current (AC) in an electrolyte between two electrodes. They work differently than other types of capacitors in that they are made with a solid dielectric material instead of an oil-based or gas-filled electrolyte. This solid dielectric material is often tantalum, hence the capacitor’s name.

The anode of the capacitor is made from strips of pure tantalum, and the cathode is made from a strip of tantalum-oxide. When an external voltage is applied across the capacitor, the solid dielectric material allows for current to flow from the anode to the cathode and back. This charge accumulation across the two electrodes, otherwise known as capacitance, is the basis of tantalum capacitor technology.

The amount of charge that can be stored in a tantalum capacitor is determined by the size of the capacitor, its voltage rating, and the tolerance of the capacitor. The capacitor’s capacitance, or charge storage capacity, is also referred to as its capacitive reactance. In other words, the reactance of the capacitor is a measure of its ability to store energy.

Advantages of Tantalum Capacitors

Tantalum capacitors are advantageous for several reasons. They have high volumetric efficiency, meaning they offer considerable capacitance in a relatively small space. They also have low equivalent series resistance (ESR), which allows for improved current transfer and higher-frequency operation. Furthermore, they’re resistant to environmental conditions, such as moisture or fluctuating temperatures, which makes them an ideal choice for use in rugged or extreme conditions. Finally, they’re cost-effective and easily available.

Conclusion

The M39003/01-5363H capacitor is an excellent choice for applications such as DC-DC converters, switching power supplies, and low impedance filtering. Its properties such as high volumetric efficiency, low ESR, and resistance to environmental conditions make it well-suited for such applications. Tantalum capacitors offer countless benefits and will continue to gain application in various industries.
