Tantalum capacitors are incredibly useful for a wide variety of applications, and the M39003/01-7220 is a great example of the sorts of parts commonly available in this type. This type of part is commonly used in portable electronics, such as cell phones and laptops, but they have plenty of potential in larger, industrial settings as well. The main advantage of a tantalum capacitor is its low profile, allowing it to fit in small spaces that would normally not be able to house larger parts. This also has the added effect of making it very heat resistant, as the capacitors are fitted very tightly to the board.

The M39003/01-7220 falls into the SMD type of Tantalum capacitor. This stands for Surface Mount Device, and refers to the fact that the capacitor is designed to mount directly onto the circuit board. As the capacitor is much smaller than its through-hole counterpart, it offers a huge amount of flexibility in terms of positioning on the board, allowing for compact and efficient designs. The part itself is designed for use in low-voltage DC circuits, providing capacitive energy storage for both high- and low-frequency applications.

The M39003/01-7220 comes in an extremely small package, just 1.5mm x 0.75mm. It has a maximum operating temperature of 125°C and a capacitance of 220µF, which, along with its size, makes it ideal for use in smaller, portable devices. The unit is also rated for a voltage of 6.3V, making it well suited to low-voltage DC circuits. Its construction is designed to minimize ESR, or equivalent series resistance, allowing for more efficient and effective power delivery.

The capacitive principle governs the way these tantalum capacitors work. Capacitance occurs when two conductors carry a charge that opposes each other. The size of the capacitor determines the amount of resistance to the flow of current, creating a so-called impedance, which is measured in ohms. When current is applied to the capacitor, it will accumulate energy in a process called charging, as the voltage across the capacitor will increase. When the current is removed, the capacitor will release the stored energy, a process called discharging, and the voltage across the capacitor will decrease.

Ultimately, the M39003/01-7220 is a great choice for a variety of applications, particularly in portable electronics, and its extremely small form factor makes it a must-have for space-constrained designs. Its low capacitance, voltage and temperature ratings also make it well suited for low-voltage DC applications, such as powering digital circuitry on cell phones and other small devices. As a result, the M39003/01-7220 can be relied upon to provide reliable capacitive energy storage in a wide variety of applications.
