Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor. They are used extensively in the electronics industry. They can be found in virtually every electronic device, from cellular phones to computers. They are available in a variety of sizes and capacitance values, from miniature surface-mount versions to large can-style capacitors.

The M39003/03-3070H is a small, cylindrical, tantalum capacitor specifically designed for use in high-power electronic circuits. It is constructed with gold plated terminations and incorporates an all-plastic body for better thermal dissipation. This device is suitable for wave soldering, has a low profile, and provides for excellent dielectric stability.

Application Field and Working Principle

The M39003/03-3070H tantalum capacitor is designed for applications that require high-temperature and frequency stability, such as motor control circuits, high-resolution analog-to-digital converters, and pulse width modulators. The device also offers exceptional stability at high temperatures, such as those encountered in digital signal processing applications, making it an ideal choice for applications that require long-term performance in extreme temperature environments.

The working principle of the M39003/03-3070H is the same as that of other types of electrolytic capacitors. An electrolyte is placed between a pair of plates, and the electric current creates a charge imbalance between the plates, allowing the capacitor to store electrical energy. The electrolyte material and geometry of the capacitor tank form the basis of its capacitance value.

Tantalum capacitors offer several advantages over other electrolytic capacitors, such as higher volumetric efficiency, lower equivalent series resistance (ESR), and lower temperature drift. Additionally, tantalum capacitors can be used in environments where very demanding capacitance requirements must be met in a small space. Finally, tantalum capacitors are more reliable than other types of capacitors, since they are less susceptible to vibration and temperature variations.

In addition, the M39003/03-3070H is particularly well-suited to applications where ultra-high temperature stability and long-term performance are required. The device offers an extended operating temperature range from -55°C to +125°C, and withstands over 1,000 hours of reverse polarity at105°C. Its tight capacitance tolerance and low ESR make it ideal for sensitive applications.

Conclusion

The M39003/03-3070H is a versatile and reliable tantalum capacitor specifically designed to perform in extreme temperature environments. With its high temperature stability and long-term reliability, along with its small size and low ESR, this capacitor is ideal for applications requiring high-performance operation. As such, the M39003/03-3070H is an excellent choice for designers of electronic circuits in need of a reliable, stable, and long-lasting capacitance solution.
