Fixed Inductors

Fixed inductors are electrical components which store energy as a magnetic field. They are made up of wire coils which are wound around a core, usually of ferrite or air depending on the frequency range and inductance. Fixed inductors are used for a variety of applications such as boosting signal levels, providing DC isolation, providing impedance matching, stabilizing voltage levels and storing energy.

The PM5022-331M is suitable for a range of different applications such as switching power supplies, inverters, PFC and DC-DC converters. It has an operating temperature range of -40 to +125 degrees Celsius and a rated current of 2.8A.

Application Field

The PM5022-331M is primarily used as an inductor for a range of different applications. Its high current handling capability makes it suitable for use in AC adapters, inverters, DC-DC converters and other switching power supplies. Its impedance matching capability makes it a good choice for RF circuits, and its high temperature rating makes it suitable for use in high temperature environments.

Working Principle

The PM5022-331M works on the principle of inductance whereby a current flowing in a wire loop produces a magnetic field. This magnetic field creates a voltage opposing the original current, thus limiting its flow. In other words, electric current flowing through an inductor creates a back-emf. The back-emf is proportional to the rate of change of the current flowing through the inductor and is usually in opposite direction of the applied voltage. Thus, inductors are able to control the flow of current, increase signal strength, and store energy.

Conclusion

The PM5022-331M is a fixed inductor suitable for a range of different applications. Its ability to control the flow of current, increase signal strength, and store energy make it an ideal choice for use in AC adapters, inverters, DC-DC converters and other switching power supplies. Additionally, its high temperature rating makes it suitable for use in high temperature environments.
