Tantalum capacitors, also known as tantalum electrolytic capacitors, are many varieties of electrolytic capacitors which use tantalum as the anode electrode. Due to its exceptional ability to resist corrosion and offer a high capacitance for its size, it is widely used in electronics applications, such as for high frequency or signal filtering, for smoothing power supply ripple, and for energy storage. Tantalum capacitors are divided into two categories, solid and wet-slug.

The M39003/03-0379/TR is one type of solid tantalum capacitor. It has a maximum operating voltage of 20 volts, a capacitance range from 0.1 µF to 47 µF, and a temperature range from -55°C to +125°C. It is commonly used for non-polarized applications, where it is usually paired with a diode to prevent reverse current in the circuit. It is also used in high frequency applications like microprocessors and digital signal processors as a timing capacitor.

The working principle of a tantalum capacitor is based on the fact that the capacitor oxide can act as a dielectric. In a tantalum capacitor, a tantalum pellet is used as the anode, while a wiring loop or MnO2 paint is used as the cathode. When a voltage is applied, charges collect on the surfaces of the tantalum pellet and the bonding wire, creating an electrical field between the two that is proportional to the applied voltage. This electrical field produces a capacitance. By adjusting the amount of oxide on the pellet and the amount of current flowing through the loop, the total capacitance of the capacitor can be altered.

The M39003/03-0379/TR tantalum capacitor is a reliable, compact, and cost-effective solution for high-frequency and low-ripple applications. Its low ESR rating ensures improved power delivery, and its wide range of available capacitances allows users to find the appropriate size for their application. The capacitor\'s operating temperature range allows it to be used in a wide variety of environments, with the added benefit of increased reliability.

In summary, tantalum capacitors are an excellent choice when it comes to electronic components. The M39003/03-0379/TR in particular is a high-performance capacitor with a wide capacitance range and low leakage current. Its wide temperature range and low ESR rating make it suitable for a variety of applications, and its high reliability makes it ideal for long-term use.
