Introduction to M39003/03-0449H Tantalum Capacitors

M39003/03-0449H is a type of tantalum capacitors, which were first developed in the 1940s and have now become widely used in a variety of consumer electronics, including computers, phones, toys, medical equipment, and other devices. Tantalum capacitors are known for their high dielectric strength and resistance to corrosion, which make them a preferred choice in many applications. The M39003/03-0449H is a radial leaded, surface mount capacitor that is specifically designed for use in capacitive power supplies.

Application Field and Working Principle

The M39003/03-0449H is used in a wide range of electronic devices, from industrial and medical instruments, to consumer electronics, and even radio-frequency applications. It is primarily known for its efficient capacitance performance, as it is able to store relatively large amounts of electric energy compared to other types of capacitors. The M39003/03-0449H is also characterized by its low-ESR (equivalent series resistance) and low self-heating, which makes it more reliable and efficient.

The unique design of the M39003/03-0449H allows it to only use two terminals, thus eliminating the need for complex mounting hardware. The capacitor can also be easily integrated into a printed circuit board (PCB) due to its small size and footprint. The M39003/03-0449H is capable of providing power to high-frequency applications by utilizing its ability to reduce ESR and low self-heating.

Like other tantalum capacitors, the M39003/03-0449H works by storing electric charge within a polished, high-capacitance dielectric layer inserted between two conductive metal plates. As an electrical field is applied, a transfer of electrical charge begins to occur, which in turn creates an electric field between the two plates. This electric field stores the energy and prevents the electric current from passing through, thus allowing it to be released and discharged when necessary, e.g. when supplying power to the circuit.

The M39003/03-0449H is capable of providing up to 1,000 volts of voltage and a capacitance of 4700 microfarads. It also features a small case size (3.2 x 6.2 x 8 mm) and a low leakage current of 0.1μA, making it a suitable choice for a variety of applications.

Conclusion

The M39003/03-0449H is a reliable and efficient capacitor designed for use in electronic devices and applications. It is able to store large amounts of electric energy, as well as reduce ESR and self-heating, which makes it suitable for high-frequency applications. The M39003/03-0449H is also known for its small size and low leakage current, making it a preferred choice for many industries and applications.
