Tantalum capacitors are an important electrical component in electronic systems ranging from simple consumer solutions to specialized military and aerospace installations. In comparison to other types of capacitors, they are extremely compact, have higher capacitance-to-volume ratios, and require less board space for installation. The M39003/01-2893 is a popular type of tantalum capacitor, offering superior electrical performance and high reliability, and is suitable for a variety of applications.

Application Field

The M39003/01-2893 is ideally suited for use in industrial and commercial applications. The capacitor offers low ESR and high capacitance in comparison to other similar products, and is able to handle temperatures up to 105°C. It is capable of storing a large amount of energy with a low equivalent series resistance, making it a widely used capacitor for power backup, digital signal processing, switched-mode power supplies, and more. The capacitor also features a low leakage rate when compared with electrolytic types, making it suitable for low transient applications.

Working Principle

Tantalum capacitors are electrolytic capacitors made from tantalum powder, and use an electrolytic form of tantalum pentoxide (Ta2O5) as the material for the dielectric. This material possesses high dielectric permittivity, making it possible to create thin dielectric layers that are capable of storing high amounts of charge for a given volume. The dielectric layer also features high electric breakdown voltages, and is able to handle rapid charge and discharge cycles. The capacitor also features a low self-discharge rate, making it suitable for longer-term energy storage applications.

The M39003/01-2893 features a negative, anode terminal, and a positive, cathode terminal. The dielectric is sandwiched between two layers of tantalum powder, with a catalyst material immersed in a polymer electrolyte. The capacitor is able to store electrical energy when a voltage is applied between the anode and cathode terminals. The energy stored in the capacitor is released when the voltage is removed, and the charge stored in the dielectric is discharged into the external circuit.

The rated voltage of the M39003/01-2893 is 10 VDC. The forward voltage drop of the capacitor is low, typically around 0.35 VDC, and the capacitor has a total capacitance of 680µF. The capacitor is also able to handle high current pulses, so it is suitable for applications requiring rapid charge and discharge cycles.

Tantalum capacitors like the M39003/01-2893 offer superior electrical performance and high reliability in a variety of applications. They are able to store large amounts of energy with a low equivalent series resistance, making them a popular choice for power backup, digital signal processing, and switch mode power supplies. The capacitor is also able to handle temperatures up to 105°C, making it suitable for industrial and commercial use.
