Tantalum Capacitors

Tantalum capacitors are polarized electrolytic capacitors that have a tantalum material as their anode. They offer great performance, reliability, and temperature stability for higher voltages and frequencies.The M39003/03-0447H is a high-performance, surface-mount, miniature Tantalum capacitor. It is composed of a two-layer tantalum anode (protected by an oxide film) and an electrolyte. The M39003/03-0447H has a maximum working voltage of 16 volts DC and a rated capacitance of 0.022 µF.Tantalum capacitors are increasingly popular in portable devices and consumer electronics. Due to their very low ESR (Equivalent Series Resistance) and ESL (Equivalent Series Inductance), they are ideal for applications that require a high capacitance-to-volume ratio.The M39003/03-0447H is ideal for bypass, decoupling, and filtering applications. Its small size and low capacitance make it suitable for use in the most space-limited applications.

Application Field and Working Principle

The M39003/03-0447H is used in a variety of applications, including consumer electronics, medical, automotive, and industrial applications. It is used in DC/DC converters, power supplies, and signal circuits. Furthermore, its high current-handling characteristics make it a suitable choice for signal filtering and noise suppression.The M39003/03-0447H has an oxide film on its surface that serves as its dielectric between the two layers of tantalum. This film holds the opposite charges of the two layers apart, creating a capacitance. When a voltage is applied, the positive charge accumulates on the anode, and the negative charge on the cathode. This charge separation establishes an electrical field between the two plates and a potential difference across the capacitor.When the voltage changes, the charges on the capacitor adjust accordingly. This circuit is completed when a current is applied, at which point the electric field between the plates increases.The dielectric properties of the oxide film, combined with the small size of the M39003/03-0447H, ensure that it retains its capacitance over time and is resistant to changes in temperature and voltage.

Conclusion

The M39003/03-0447H is an ideal choice for a wide range of applications. Its small size and high capacitance-to-volume ratio make it ideal for use in space-limited applications. Its high current-handling characteristics make it suitable for signal filtering and noise suppression. Finally, its dielectric properties ensure that it retains its capacitance, makes it resistant to changes in temperature and voltage.
