Tantalum Capacitors

A tantalum capacitor is an electronic component composed of a pellet of tantalum metal as an anode, covered by an insulating oxide layer that forms the dielectric, surrounded by conductive material as a cathode. This type of capacitor is especially suitable for high-frequency and radio frequency applications and usually takes the form of a disc with two layers of metallisation that form the electrodes.

195D475X0002S2T application field and working principle

The 195D475X0002S2T is a high-frequency and RF frequency application device used in various types of circuitry, including frequency multipliers, voltage regulators and high performance signal applications. Moreover, due to the high temperature stability of tantalum capacitors, this device is often used in applications involving temperature cycling or shock. In addition, tantalum capacitors are a type of electrochemical capacitor that use tantalum anode and a conductive electrolyte as the cathode. The tantalum anode is a porous pellet that is used to form a dielectric layer on the anode. The conductive material is the second part of the capacitor, or the cathode. When a voltage is applied to the component, the current will flow and charges the dielectric layer, thus forming the capacitor. The capacitance of the tantalum capacitor is determined by the geometry, area, and material properties of the component, as well as the capacitive elements present.

The 195D475X0002S2T component features an operating voltage rating of 475V and a capacitance of 2.2μF. In terms of applications, the 195D475X0002S2T component is ideal for use in temperature cycling and shock applications, as the operating temperature range for the component is -55°C to +125°C, with improved performance at temperatures above 75°C. In addition, the component features breakdown voltages of 1.2kV (40°C) and 850V (70°C) and can handle peak current of 2A. Also, the component has a tolerance of ±20%, which is fairly standard for tantalum capacitors.

Finally, the component has a leakage current rating of 1.0 μA and an equivalent series resistance (ESR) of 0.15 Ohms. The ESR rating indicates the amount of resistance that is present when the device is used for energy storage and conversion. In order for the component to perform its intended functions, the ESR must be lower than the total impedance of the circuit, as higher resistance increases the overall power loss in the system.

In conclusion, the 195D475X0002S2T tantalum capacitor is a high-frequency and RF frequency application device ideal for use in temperature cycling and shock applications. In addition, the component has a capacitance of 2.2μF and a voltage rating of 475V and features a tolerance rating of ±20%, a leakage current of 1.0 μA and an ESR of 0.15 Ohms.
