Tantalum Capacitors

Tantalum capacitors are a type of capacitive electronic component that uses the principle of electrochemical surface-containing materials to store energy in an electrical field. This type of capacitor is commonly used in modern electronics, and is especially useful for applications that require high-stability and high-current capacity. The M39003/01-8294/HSD is one such tantalum capacitor. Its application field and working principle are described in this article.

Application Field

The M39003/01-8294/HSD is a Solid Electrolytic surface-mounted tantalum capacitor. It is available in two configurations - Surface Mount (SMT) and Through-Hole (TH). Both of these configurations allow for a wide range of applications, including power supplies, instrumentation, and electronic data processing and control systems. The SMT version provides a smaller, easier to install package, and both offer exceptional noise absorption and filtering performance.

This particular tantalum capacitor is rated for 2,500uF at a voltage of 35 volts, a capacitive-tolerance of -20%/+80%, and an impedance of less than 20 ohms from zero to beyond-specified operating frequencies. The limited size and ultracapacitive current-capacity of the M39003/01-8294/HSD allows it to be used in a variety of power-requiring environments such as medical equipment, high-end audio, and automotive and avionics applications.

Working Principle

Tantalum capacitors, including the M39003/01-8294/HSD, use the surface-containing materials of tantalum, which is an extremely stable element whose properties make it an excellent choice for use in capacitors. This type of capacitor is formed when the tantalum and an electrolyte are sandwiched between two electrodes. This arrangement creates an electrical field, which has a capacitance value that is influenced by the surface area and thickness of the tantalum. This field serves as the capacitor’s storage for electric energy.

The electrolyte acts as a dielectric, providing the electric insulation between the two electrodes and increasing the capacitor’s efficiency. In addition, the surface-containing materials of tantalum provide an additional benefit in the form of increased corrosion resistance. As a result, the M39003/01-8294/HSD is more reliable and longer lasting in environments requiring moisture protection.

Conclusion

The M39003/01-8294/HSD is a solid electrolytic tantalum capacitor that offers a range of features and benefits, making it ideal for use in a variety of applications. Its efficient design provides excellent capacitance-tolerance and noise-absorption, while its small size and high current-capacity makes it particularly useful in power-hungry environments. Finally, its superior corrosion resistance also makes it a reliable choice for applications that require moisture protection.
