Working Principle

At the molecular level, the 225P18491XD3 film capacitor utilizes a molecular network of conductive polymers that can quickly store and release energy when an electric field is applied. This electrochemical reaction creates a charge that can be used for various tasks. When the current flows through the capacitor, the electrochemical reaction between the positive and negative terminals of the capacitor causes the ions of the electrolyte to move, generating an electric charge.

The 225P18491XD3 has a unique three-in-one design that allows it to be used in multiple applications. The capacitor has three distinct layers; a cathode carrier layer, an electrolyte layer and an anode layer. The cathode carrier layer contains a positive terminal and acts as a current collector. The electrolyte layer contains an electrolyte and acts as the dielectric material. The anode layer acts as the negative terminal and allows the electrons to travel from one end of the capacitor to the other.

When the capacitor is connected to a power source, electricity flows through the electrolyte layer, generating an electric field. The electric field causes the ions of the electrolyte to move, creating a charge that can be used for various tasks. The 225P18491XD3 film capacitor also has a low ESR and low ESL, making it ideal for high-voltage and long-term load applications.
