Tantalum capacitors are widely used in a variety of electronic components. The M39003/01-7254/TR is a type of tantalum capacitor, and it has a wide range of applications. This article will discuss the application field and working principle of the M39003/01-7254/TR.

Application Field of the M39003/01-7254/TR

The M39003/01-7254/TR is a type of miniature, surface-mounted, electrolytic tantalum capacitor with a capacitance of 47 μF. It is mainly used in communications and consumer electronics, such as mobile phones, GPS devices, and other devices that require a high capacitance in a small package.

The M39003/01-7254/TR has several advantages, including an excellent frequency characteristics, low ESR, low impedance, higher capacitance than ceramic capacitors, and high reliability. Its small size also makes it perfect for applications where space is at a premium, such as in mobile phones and laptop computers.

Working Principle of the M39003/01-7254/TR

The M39003/01-7254/TR is a type of electrolytic tantalum capacitor, which stores energy by utilizing the electrochemical reactions between two electrodes: one is an anode, the other is separated from the anode by an electrolytic solution. The anode is constructed from a tantalum pellet, and the electrolyte is a solution of ions. When a voltage is applied to the electrodes, the anode acts as an ion donor, creating a positive charge on the anode surface. This attracts the negatively charged ions from the electrolyte, forming a layer of ions on the anode surface.

When the voltage is removed from the electrodes, the attractive force between the anode and the ions is weakened, and the ion layer on the anode breaks down. This causes the capacitor to discharge, releasing the stored energy. The amount of energy stored by the capacitor is determined by the capacitance, which is proportional to the size of the anode and the density of the ion layer. Due to its high capacitance, the M39003/01-7254/TR is able to store large amounts of energy in a small package.

Conclusion

The M39003/01-7254/TR is a type of miniature, surface-mounted, electrolytic tantalum capacitor with a high capacitance and excellent frequency characteristics. It is well-suited for applications where space is at a premium, such as mobile phones and laptops. Its working principle is based on the electrochemical reactions between two electrodes: one is an anode, the other is separated by an electrolytic solution. When the voltage is applied to the electrodes, the anode acts as an ion donor, creating a positive charge on the anode surface and storing energy. When the voltage is removed from the electrodes, the attractive force between the anode and the ions is weakened, and the capacitor releases the stored energy.
