Tantalum capacitors are a type of capacitor with a tantalum electrolyte sealed in an anode. These capacitors are widely used in a variety of electronic gadgets, including radios, televisions and cell phones. The M39003/03-2048/TR is a type of tantalum capacitor specifically designed for line-operated systems. It is used in applications that require high capacitance and low series resistance. The following sections will discuss the application field and working principle of the M39003/03-2048/TR tantalum capacitor.

Application Field

The M39003/03-2048/TR is a high-performance tantalum capacitor with an operating temperature range of -55°C to +105°C. It is available in three capacitance values: 10µF, 20µF and 30µF. The device is capable of withstanding a maximum operating voltage of 50VDC and is designed for use in applications with high ripple currents. The capacitor is also well suited for use in audio power amplifiers, pulse motor drives, timing, and mid-frequency filtering. The device is also commonly used in high-constant-volume applications, such as fuel injectors, which require high energy capacitance.

Working Principle

The M39003/03-2048/TR capacitor consists of a tantalum anode and two anion-selective membranes, which form the capacitor’s dielectric layer. A small amount of tantalum pentoxide powder is placed between the two membranes, forming a capacitor in a sandwich-type configuration. The anode is then sealed with a conductive material, which is held in place by a special conductive epoxy. The capacitance of the capacitor is determined by the area of the capacitor and the thickness of the dielectric layer.

When a voltage is applied to the device, the anode and cathode are charged with an equal amount of electrons. This creates a potential difference between the two plates. As the capacitor charges, the voltage across the plates increases until the anode and cathode are saturated. At this point, the capacitor is said to be in a state of equilibrium, and the exchange of electrons between the plates ceases.

Once the capacitor is charged, it can be used to store energy. When the charge on the capacitor begins to decrease due to a current draw, the capacitor releases the stored energy and the voltage across the plates decreases. This process continues until the current draw is balanced with the charge on the capacitor, resulting in an equilibrium state again.

Conclusion

The M39003/03-2048/TR tantalum capacitor is a high-performance device designed for use in applications with high ripple currents. It has a wide operating temperature range and is available in three capacitance values. The capacitor is formed with a tantalum anode and two anion-selective membranes, and is capable of storing energy when a voltage is applied. The device is commonly used in audio power amplifiers, pulse motor drives, and high-constant-volume applications.
