Working Principle

The F971E225MBAHT3 is a tantalum capacitor built with two metallic layers separated by a dielectric layer. The two metallic layers act as the two plates in the capacitor, where one is the anode (-) and the other is the cathode (+). There is a special dielectric, typically a tantalum oxide, between the two plates that creates a barrier between them. This barrier’s electric field prevents a direct flow of current between the two plates and creates a capacitance value for the unit.

When voltage is applied across the two plates, an electric field is created. The electric field induces a current flow from the cathode to the anode and the capacitor begins to charge. Once the electric field has reached equilibrium, the capacitor becomes charged and the current stops flow. The capacitance value of the tantalum capacitor is dependent on the size of the two plates and the dielectric between them.

The F971E225MBAHT3 is a reliable capacitor and is designed for automotive and industrial applications. Its wide operating temperature range makes it suitable for a variety of applications, and its ESR and ESL characteristics make it suitable for high-temperature environments. Its two plates and dielectric layer work together to form a capacitor with a specific capacitance value. Overall, the F971E225MBAHT3 is an ideal choice for automotive and industrial applications.
