Tantalum capacitors are capacitors that use tantalum as the anode metal. They consist of a pellet of tantalum metal encased in an insulating oxide layer, which is usually enclosed in a non-conducting cylindrical can formed from aluminum or plastic. Tantalum capacitors are among the most commonly used capacitors in electronic circuits, and are widely used in both commercial and military electronic equipment.

The M39003/01-8349H is an example of a tantalum capacitor. It is designed for use in aviation, aerospace, and other high-reliability applications. It has a rated capacitance of 4.7μF and a working voltage of 85V. It features a low equivalent series resistance (ESR) of 8 milliohms and a low dissipation factor (DF) of 3% at 100Hz.

The M39003/01-8349H has a number of advantages over other types of capacitors, including a smaller size, improved reliability, and better performance in high-temperature environments. The use of tantalum for the anode metal allows the device to be constructed with a smaller footprint than other capacitor types, which is important in densely packed circuit boards. The use of the oxide layer also provides excellent electrical insulation, making it highly efficient and reliable, even in extreme temperatures.

The working principle behind the M39003/01-8349H is simple. When a voltage is applied across the two plates of the capacitor, a current causes the electrons to move from one plate to the other, creating a charge on the plates. The voltage applied across the plates determines the amount of charge stored in the capacitor, which is equal to the product of the capacitance and the voltage. When the current is removed, the charge remains stored in the capacitor until the voltage is reversed or dropped below the rated value, causing the charge to dissipate.

The M39003/01-8349H is a highly reliable and efficient device, making it suitable for use in a range of applications such as power supply decoupling, signal filtering, DC blocking, and energy storage. It is designed for use in high-reliability applications in the aviation, aerospace, and military sectors. Its small size and low ESR mean it is ideal for use in densely packed circuit boards, making it a valuable addition to any high-performance system.
