TARR105M035

Tantalum capacitors are a widespread type of capacitor used in many different electronics applications. They are popular for their high capacitance values, low ESR (Equivalent Series Resistance), high tolerance range, and low leakage current. A tantalum capacitor, such as the TARR105M035, is a type of electrolytic capacitor that uses a layer of tantalum as the anode, and a wet electrolyte as the cathode. This capacitor is particularly well-suited for use in high-efficiency, high-frequency, and high-temperature applications such as RF circuits, power supplies, and motor control.

Application field and working principle

The TARR105M035 is a cylindrical tantalum capacitor that is particularly well suited for high current and high- Frequency applications. It features a voltage rating of up to 35 Volts, capacitance of 105μF, and a tolerance of ±10%. The capacitor’s high capacitance allows it to be used in a variety of power and signal conditioning applications such as snubbers, MRI systems, and power supplies. It can also be used to provide transient voltage suppression in typical electronic systems.

The working principle behind a tantalum capacitor starts with an oxide layer that is formed on the tantalum anode when it is first placed into service. As an electric current is passed through the capacitor, the oxide layer grows thicker, increasing the surface area of the anode. The more surface area there is, the greater the electric field capacitance, which in turn enables the capacitor to store more energy. As the voltage across the capacitor increases, the oxide layer grows even thicker, thus increasing the capacitor’s capacitance even more. This phenomenon is known as capacitance charging, and is the driving force behind the capacitor’s ability to store energy.

The tantalum capacitor is also highly efficient. Its low internal impedance and high dielectric breakdown are enough to sustain even high peak currents for very short duration. The capacitor’s low ESR is enough to keep power losses relatively low, even when handling high currents.

Conclusion

The TARR105M035 tantalum capacitor is an important component for high current, high-frequency, and high-temperature applications. Its ability to store high capacitance in a small form factor, along with its low ESR, makes it an ideal choice for many power supply and signal conditioning applications. Its efficiency also makes it highly suitable for applications such as transient voltage suppression.
