Introduction to Tantalum Capacitors

Tantalum capacitors are electronic components used in a variety of applications including signal decoupling, power filtering, bypassing, energy storage, and switching power supplies. They have a high capacity per unit volume and are commonly used to reduce the physical size of a capacitor bank in circuits. Tantalum capacitors use a tantalum metal powder as the electrodes and an electrolytic solution as the dielectric material.

M39003/09-0382 Application and Working Principle

M39003/09-0382 is a molded surface-mount tantalum capacitor manufactured by Vishay. It is a low-profile, low-profile, general-purpose, E type, miniature capacitor design with a capacitance range of 1uF to 100uF. The capacitor’s rated voltage is 6.3V, with tolerance ratings of ±20%. M39003/09-0382 capacitor is extremely reliable and offers long-term performance with excellent stability against aging and temperature variations. It is a simple construction consisting of two lead-free terminals, a sintered tantalum anode and cathode, and the dielectric material of the electrolytic solution. The anode and cathode are usually made from tantalum mandrels, which have a structure like a spring that wraps around the other components of the capacitor.When a voltage is applied, a thin layer of electrolytic solution forms around the anode and cathode. This forms a barrier between the anode and cathode which prevents direct current conduction through the capacitor. The electrolyte also acts as an insulator between the anodes and cathodes, allowing only the alternating current to flow. This results in energy storage and provides a capacitance value determined by the anode and cathode materials, as well as the dielectric material.The main application of the M39003/09-0382 tantalum capacitor is for filtering and noise reduction in power supplies, microprocessors, amplifier circuits, and digital circuits. It is a reliable component that offers a long-term life with excellent stability under varying temperatures. It also has a low profile design which helps reduce the physical size of the component making it an ideal solution for applications that require a small form factor.

Conclusion

The M39003/09-0382 is an E type, molded surface-mount miniature capacitor designed for general purpose applications. It is a reliable and stable component with a low-profile design making it suitable for high-density applications. The capacitor offers a capacitance range of 1uF to 100uF and a rated voltage of 6.3V with tolerance ratings of ±20%. The M39003/09-0382 is a reliable component that offers excellent long-term performance and is commonly used in power supplies, microprocessors, amplifiers, and digital circuits for filtering and noise reduction.
