Tantalum capacitors are electronic components which use tantalum as the anode material in their construction. They are widely used due to their high capacitance, low leakage current and low SoR values. The 173D334X9050V is a type of tantalum capacitor with the anode-cathode gap of 0.1 um and the anode-cathode voltage rating of 20V, which makes them suitable for a wide range of applications.

The 173D334X9050V tantalum capacitors are mainly used in high density, low voltage applications such as battery circuitry, lighting circuits, DC-DC converters and AC power supplies. They are also used in low frequency radio circuits, RFID readers and data acquisition systems.

The working principle of the 173D334X9050V tantalum capacitors is based on the electrochemical double layer capacitance. The working principle of a capacitance is based on the fact that when two conductors are placed in close proximity, their electric fields interact and store a charge. In the case of tantalum capacitors, the two conductors are typically made of tantalum and titanium alloys, and the electrical charge is stored between the two conductors.

The tantalum capacitors are composed of a ceramic dielectric layer, a tantalum anode, a titanium cathode and a titanium current collector. The tantalum anode creates a positive electric field, while the titanium cathode creates a negative field. When a voltage is applied across the tantalum anode and titanium cathode, the electric field between them induces a current in the titanium current collector, thus forming a capacitance.

The capacitance of the 173D334X9050V tantalum capacitor is also highly dependent on the temperature of the environment. At higher temperatures, the capacitance decreases due to the thermal expansion of the ceramic dielectric layer and the increased dielectric constant of the tantalum anode. At lower temperatures, the capacitance increases due to the reduced thermal expansion of the ceramic dielectric layer and the decreased dielectric constant of the tantalum anode.

The 173D334X9050V tantalum capacitors have a wide operating temperature range of -40°C to +105°C and a low ESR value of 0.25 ohms. The capacitors are also RoHS compliant and have a leakage current of 0.2 mA at 105°C.

In summary, the 173D334X9050V tantalum capacitors have a wide range of applications where high capacitance and low leakage current is needed. They have a wide operating temperature range, low ESR value and a leakage current of 0.2 mA, which makes them suitable for a wide range of applications.
