9220-04

Fixed inductors are electrical components that are created to store electromagnetic energy by means of a magnetic field. This energy can then be released into an electrical circuit for various uses. Inductors are used to store electrical energy during periods of low, or no, current flow, and can be used to filter specific frequencies from a signal. The 9220-04 application field and working principle of an inductor are derived from four basic properties - inductance, resistance, capacitance, and power conversion efficiency.

Inductance

Inductance is the property of the inductor that most closely pertains to its functionality. It refers to the ability of the inductor to store electrical energy in the form of a magnetic field. The inductance of an inductor is determined by the number of turns in the inductor\'s winding, as well as the core material it is wound with.

Resistance

The resistance of an inductor is also an important component of its functionality. Resistance is the opposition to the flow of current in an electrical circuit. This can be beneficial in filtering frequencies, particularly high-frequency signals, by slowing or speeding up the current flow.

Capacitance

Capacitance is the ability of the inductor to store and release energy within a specific time frame. This is helpful when designing energizing and de-energizing parts of the circuit, as well as avoiding the buildup of thermal energy within the inductor.

Power Conversion Efficiency

Power conversion efficiency of an inductor is related to its ability to convert electrical energy to mechanical energy. This is important when creating variable magnetic fields, as well as when controlling circuits that require high-frequency switching.

9220-04 Application Field and Working Principle

The 9220-04 is an inductor designed for flyback converters for DC-DC conversion applications. The inductance of the 9220-04 is 1.3mH, and the resistance is 0.288 ohms. The 9220-04 is able to support a 1.0A current in a 100 kHz power range, making it suitable for a variety of applications. It also features excellent power conversion efficiency, with a maximum efficiency of 90% when used with high frequency switching.

The 9220-04 works on the principle of magnetic induction. It uses an alternating current to build up a magnetic field, storing energy in that field. When the current is interrupted, energy is released from the magnetic field, enabling DC-DC conversion. All of this is possible because of the inductor\'s ability to store electrical energy in the form of a magnetic field, and then release it in the form of a current.

The 9220-04 is just one of many fixed inductors on the market, and has specific applications and working principles that make it unique. It is an excellent choice for flyback converters, due to its high efficiency and low resistance, allowing it to store power efficiently and quickly.
