Tantalum Capacitors : TPSA474K025R7000 application field and working principle
Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of electrolytic capacitor that utilizes the property of Tantalum for capacitance. They are widely used for filtering and bypassing in a variety of electronic devices. This article looks at the application field and working principle of an example tantalum capacitor, the TPSA474K025R7000.Application Field of TPSA474K025R7000
The TPSA474K025R7000 is a high capacitance, high voltage, surface mount tantalum capacitor. It is generally used for high voltage applications, such as DC/DC converters, power supplies, and DC motors.The distinctive features of the TPSA474K025R7000 include its high voltage rating (35V DC), high capacitance (47µF to 470µF), and low ESR (Equivalent Series Resistance). This makes the TPSA474K025R7000 highly suitable for use in power supplies with high power requirements and high voltage systems.The TPSA474K025R7000 also offers greater flexibility than many other tantalum capacitor solutions, as it is available in a variety of sizes, voltages, and capacitance ratings. This ensures that it is able to meet the specific needs of different applications.Working Principle of TPSA474K025R7000
The working principle of a tantalum capacitor is based on a process that relies on the deposition of a layer of tantalum oxide on the surface of the anode. This layer acts as a barrier between the anode and cathode, effectively creating a capacitor.The anode of a TPSA474K025R7000 tantalum capacitor is typically composed of a sintered tantalum powder. This powder is compressed and then heated in an oxygen-free environment to form a porous anode. The porous anode is then covered with a layer of tantalum oxide, which acts as the dielectric.The cathode of the TPSA474K025R7000 tantalum capacitor is composed of a conductive solid electrolyte. This electrolyte acts as a medium for the supply of electrical energy. When the capacitor is charged, electrons move through the dielectric and into the cathode, where they are stored.The capacitance of the TPSA474K025R7000 capacitor is determined by the amount of current that can be passed through the dielectric. This is determined by the thickness of the tantalum oxide on the anode and the surface area of the cathode. The higher the current and the thicker the layer of tantalum oxide, the greater the capacitance of the capacitor.Conclusion
The TPSA474K025R7000 tantalum capacitor is a high voltage, high capacitance electrolytic capacitor. It is suitable for a variety of high voltage applications, including DC/DC converters, power supplies and DC motors. The working principle of this capacitor is based on the deposition of tantalum oxide on the anode and a conductive solid electrolyte on the cathode. This produces a capacitor with a high capacitance rating, suitable for high power requirements.The specific data is subject to PDF, and the above content is for reference
