Tantalum capacitors are an electrolytic type of capacitor that uses tantalum pentoxide as a dielectric. The voltage rating of the capacitors depends on the quality of the dielectric and the amount of charge it can hold. This article will discuss the M39003/03-0282/98 application field and working principle as an example of a tantalum capacitor and its use in various applications.The M39003/03-0282/98 is a radial leaded, commercial grade tantalum capacitor with a voltage rating of 28V. It is designed with a solid, conductive polymer cathode capable of holding up to 10,000 hours at 80℃. Its capacitance range is from 2pF to 0.33uF, and its operating temperature range is from -55℃ to +125℃. This capacitor can also withstand relatively high levels of humidity and vibration.The working principle of the M39003/03-0282/98, as is the case with all tantalum capacitors, is based on Faraday’s Law of Capacitance, where a voltage applied between two electrodes causes an equal potential difference between them. The electrodes of a tantalum capacitor are either manganese-dioxide or conductive polymer, with the oxide layer or polymer acting as a dielectric. When a voltage is applied between the electrodes, a current is drawn, charging the capacitor. The current is determined by the capacitance, voltage, and the capacitive reactance of the circuit. As the capacitor charges, the potential difference across the electrodes reaches a steady-state, and the current decreases, eventually reaching zero. The charge on the capacitor then remains constant, making the capacitor an ideal energy storage device.The M39003/03-0282/98 is used in various applications, including telecommunications, automotive electronics, computers, embedded systems, power supplies, audio, and medical devices. Its high voltage rating makes it well suited for high voltage circuits, as it can handle rapid changes in voltage without significant losses in energy storage or performance. Additionally, its minimal current leakage and high resistance to harsh environmental conditions make it suitable for installations in damp or hazardous locations.In conclusion, the M39003/03-0282/98 is a commercially available, radial leaded, high voltage tantalum capacitor. It has a voltage rating of 28V and a capacitance range of 2pF to 0.33uF. It is designed to withstand high levels of humidity and vibration, and can withstand temperatures ranging from -55℃ to +125℃. It is widely used in a variety of applications, including telecommunications, automotive electronics, computers, embedded systems, power supplies, audio, and medical devices.
