Tantalum Capacitors

Tantalum capacitors are a type of capacitor that are typically characterized by their small size, high capacitance values, and high reliability. They are typically constructed with a metallic oxide cathode material, an electrolytic solution, and two electrodes. The M39003/01-2964/T99 model of tantalum capacitor is a radial leaded surface mount capacitor in a molded case made of a mixture of polypropylene and ceramic. It is designed to have a capacitance value of 470uF with a tolerance of 10%. The capacitor has a maximum operating temperature of 85 degrees Celsius and a maximum voltage rating of 16V.

Application Field

Tantalum capacitors, and specifically the M39003/01-2964/T99 model, are commonly used in a variety of applications. These range from automotive, electonic instrumentation, and lighting applications, to military, office automation, telecommunications, and other audio-visual applications. The small size and high capacitance value of the capacitor makes it an ideal choice for many applications. Its improved reliability due to the use of a metallic oxide cathode material can make it an attractive option to designers in the military, automotive, and telecommunications fields.

Working Principle

Tantalum capacitors, like other capacitors, store and release electrical energy. They function by storing all types of electrical charges on the two electrodes, one positive and one negative, and then releasing them from the negative electrode into the external circuit. This process is regulated by the dielectric of the capacitor which separates the two electrodes. The higher the dielectric constant of the capacitor, the more energy it can store and release.

The M39003/01-2964/T99 model of tantalum capacitor uses a polypropylene and ceramic mixture dielectric. This dielectric has a higher capacitance value than other dielectrics, such as tantalum oxide dielectrics, and provides superior resistance to leakage and temperature stability, making it a great choice for high-stability applications. Additionally, the use of a metallic oxide cathode offers a low-resistance path for electrons, reducing internal losses and improving the capacitor’s efficiency.

Conclusion

The M39003/01-2964/T99 model of tantalum capacitor is an excellent choice for a wide range of applications due to its small size, high capacitance value, and improved reliability. Its use of a polypropylene and ceramic mixture dielectric provides superior resistance to leakage and temperature stability. The use of a metallic oxide cathode ensures low-resistance electron paths for improved efficiency. Together, these features make the M39003/01-2964/T99 model of tantalum capacitor a great choice for engineers looking to maximize reliability and performance.
