Tantalum capacitors feature higher capacitance values in a more compact size compared to film or aluminum electrolytic capacitors. As their utilization increases, the selection of the correct capacitor for a given application also becomes critical. The TAP474M035DTS is a chip type combining tantalum capacitor with a protective circuit which decreases the possibility of failure due to an overcurrent or overvoltage application. In this article, its application field and working principle are going to be discussed. Application fieldThe TAP474M035DTS is used in switching power supply, DC-DC conversion applications, or any other application where a high-reliability and small size capacitor is needed. It is especially suitable for power factor correction, power supply circuits, and output smoothing, because it has excellent low-impedance characteristics and good temperature characteristics. Its high-temperature tolerance and high ripple current ratings also make it well suited for applications demanding high reliability, such as automotive and industrial systems.Working principleTAP474M035DTS chip type can withstand a large current and a large peak voltage due to its protective circuit. Its internal circuit consists of a P-type MOSFET, an N-type MOSFET, a voltage divider, and two resistors. The P-type MOSFET works as a load, and the N-type MOSFET works as a switch. The voltage divider reduces a large peak voltage to a level that is below the maximum operating voltage of the capacitor by using resistors as its components. In addition, the current-limiting resistors reduce the instantaneous peaks current to a level that is below the maximum surge current rating of the capacitor. Another important factor of the TAP474M035DTS is its self-healing property. When the overcurrent or overvoltage occurs the chip detects it, shuts down the circuit, and the self-healing process initiates. During the process, evaporation reduces the oxide layer, thus reducing the leakage current and restoring the capacitor to its normal state. ConclusionThe TAP474M035DTS is a chip type combining tantalum capacitors with a protective circuit which decreases the possibility of failure due to an overcurrent or overvoltage application. It has excellent low-impedance characteristics and good temperature characteristics, making it suitable for power factor correction, power supply circuits, and output smoothing applications. Its self-healing property is also a great advantage as it restores the capacitor to its normal state after an overcurrent or overvoltage event.
