Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of electrochemical capacitor. They are widely used due to their small size and low ESR (equivalent series resistance).

Specifically, the M39003/01-8284 tantalum capacitor is a hermetically sealed, surface-mount device. It has a 5.9 x 2.1 mm body, making it very suitable for surface-mount applications. It operates at an input voltage of 6.3 V, and it features a leakage current of 3 μA and an insulation resistance of 1000 MΩ.

Application field

The M39003/01-8284 capacitor is primarily used in high-frequency RF (radio frequency) power amplifiers and high-voltage converters as a filter or resonator, as it helps reduce noise and improve the quality of signals. Additionally, it is also used in other fields such as automotive electronics, consumer electronics, medical electronics, and so on.

Working Principle

Tantalum capacitors feature an anode that is composed of a porous, passivated sintered material that is usually composed of tantalum pentoxide. The cathode is typically composed of a silver-plated manganese dioxide. To increase the capacitor\'s capacitance, the anode is filled with an electrolyte solution that reduces the electrical resistance between the anode and the cathode.

When a voltage is applied to the leads of the tantalum capacitor, the anode\'s surface area will increase, thus increasing the capacitor\'s capacitance. This is due to the electrochemical reaction between the electrolyte and the anode. As the capacitance increases, the current flowing through the capacitor will also increase, thus decreasing the device\'s internal resistance.

Tantalum capacitors are also highly resistant to temperature and moisture, making them ideal for use in high-temperature or humid environments. Additionally, they are also able to store energy, making them useful for energy storage applications.
