The tantalum capacitor is used in various electronic circuits due to its excellent voltage stability and long service life.

The working principle of M39003/03-0482H is based on the principles of a conventional capacitor, which charges and discharges electricity through its electrodes. The capacitor consists of two electrodes, the anode and the cathode. In a tantalum capacitor, the anode is made of a tantalum foil and the cathode is made of a tantalum oxide layer. During charging, the anode is positively charged and the cathode is negatively charged. When a voltage is applied to the capacitor, electrons move from the cathode to the anode, while ions move from the anode to the cathode, creating a charge on the capacitor. The capacitance of the capacitor is determined by the amount of charge stored on the capacitor.

In addition, the M39003/03-0482H has a self-healing characteristic, which is very important in power management where overcharging can occur. The self-healing characteristic of the capacitor means that it can effectively recover from overcharging if the voltage is below a certain level, and thus providing improved reliability for the electronic circuits.

M39003/03-0482H tantalum capacitors can provide excellent performance in various electronic applications due to their high reliability, high capacitance, low profile, and wide temperature range. In addition, they are also highly resistant to humidity and feature a self-healing characteristic that makes them suitable for power management applications.
