Working Principle

The M39003 capacitors use tantalum as their dielectric layer. Tantalum is a heavy, ductile metal which has a high melting point and is resistant to corrosion, making the M39003 devices able to work well in a wide range of environmental conditions. The dielectric layer is held between two electrodes; the anode and the cathode. The anode is constructed of a tantalum metal oxide, and the cathode is an electrolytic-doped tantalum layer.

The working principle of the M39003 capacitors is based on the fact that the dielectric layer insulates the two electrodes from one another, allowing electric charge to accumulate on each one. This then creates a potential energy difference between the two electrodes as voltage is applied. As the current flows through the device, charge can accumulate on the electrodes, resulting in a stored electrical energy.

When the capacitors are no longer under voltage, as the energy accumulates, the dielectric layer slowly forces it out, allowing the stored energy to dissipate. The rate at which charge moves through the capacitors determines how quickly the capacitor will become discharged.

In addition to this, the M39003 capacitors have a low internal resistance to ensure that charge moves quickly through the system without significant drop in voltage. This ensures that the capacitor will remain stable and reliable over its lifetime.

The M39003 capacitors are able to withstand high temperatures, making them ideal for use in automotive and industrial applications. They are also able to cope with high levels of shock and vibration, ensuring they are suitable for use in a wide range of applications.

Overall, the M39003 capacitors offer a wide range of advantages over traditional capacitors, including high reliability, small footprints and a wide temperature range. They are also ideal for use in high frequency applications, and are able to withstand high levels of shock and vibration.
