Working Principle of ERHA551LGC272MDF0M

The working principle of ERHA551LGC272MDF0M is based on the Faraday law of electrolysis, which states that when an electric field is applied to an electrolyte, ions are forced to move, resulting in the separation of electric charge. This can be used to create capacitors with a higher capacitance than air-filled capacitors.

In order to create the desired capacitance, a layer of oxide-coated aluminum foil is placed in an electrolyte solution, allowing ions to transfer between the aluminum foil and the solution. As a result, a charge is created between the two electrodes, allowing for an electric current to flow freely between them. This charge is stored in the oxide layer and can be used to provide current when an electrical signal is applied.

The ERHA551LGC272MDF0M also features an electrolyte that has been formulated to resist the effects of aging. This feature provides a long life and superior reliability, allowing for the capacitor to be used in demanding applications. The ERHA551LGC272MDF0M also has a wide temperature range, making it suitable for use in both hot and cold conditions.
