Working Principle

The M39003/09-4051H/98 is a type of tantalum capacitor. It works on the principle of electrochemical double-layer capacitance (EDLC), commonly known as a supercapacitor. This type of capacitor has an anode and a cathode. The anode is typically made from a porous tantalum powder, while the cathode is usually constructed from an electrically conductive material. Between the two is an electrolytic solution that allows electrons to move freely between the two plates.

When a voltage source is applied, ions from the electrolytic solution migrate to the plates. The ions are attracted to the plate with the opposite charge, resulting in an electric double layer. This double layer provides the capacitance of the device. When the voltage source is removed, the ions return to their original state, retaining the stored energy.

The M39003/09-4051H/98 is designed to provide reliable power storage in a wide range of applications. It has an operating life of 2000 hours at 125°C, which makes it well suited for high-temperature environments. Additionally, its low ESR ratings ensure that the device is capable of handling high-current surges with minimal resistive losses.
