Fixed Inductors: ELJ-RG3N9DF Application Field and Working Principle

Fixed inductors are electronic components which are used to improve or change electrical current flow in circuits to suit particular application needs. A fixed inductor, such as the ELJ-RG3N9DF, is an inductor with a preset inductance that cannot be adjusted after manufacture.

ELJ-RG3N9DF Application Field

The ELJ-RG3N9DF is applicable in DC to DC converters, power supplies, switching regulators, EMI filters, power supply filtering, transformer coupling, DC blocking, resonant circuits, and noise suppressors. It is ideal for use in power supply designs with pulse width modulation, step-down, step-up, and inverter topology.

ELJ-RG3N9DF Working Principle

The ELJ-RG3N9DF works by passing a current through a coil of wire, which then creates a concentric magnetic field. When current is applied to the coil, it creates a field that is equal to the current multiplied by the number of turns in the coil. This field is called inductance. Inductance is the property of a coil of wire to resist any change in the current flowing through the circuit.

As current flows through the ELJ-RG3N9DF, a voltage is generated, the magnitude of which is proportional to the rate of change of the current flowing through the inductor. This voltage is called the “back emf”. The back emf is used to oppose any changes in the current flowing through the circuit, thus limiting the amount of current that can pass through the inductor. In other words, the ELJ-RG3N9DF is used as a voltage regulator, by introducing a voltage drop across the inductor, which helps to regulate the voltage and current in the circuit.

The ELJ-RG3N9DF is also used in RF applications, to filter out unwanted signals from a circuit or signal path. By introducing a high frequency inductor into the circuit, the desired frequencies are allowed to pass, while the unwanted frequencies are blocked or significantly reduced in magnitude.

The ELJ-RG3N9DF is a versatile and reliable component which can be used in a wide variety of applications. It has a low profile which makes it suitable for space constrained applications, and a high saturation current rating, making it ideal for high power circuits. Its inductance is stable over temperature, thus it is suitable for use in high temperature applications. It also has good heat dissipation properties, and is resistant to shock and vibration.

Conclusion

The ELJ-RG3N9DF is a type of fixed inductor which is highly versatile and suitable for many applications. It is used in DC-DC converters, EMI filters, power supplies, transformer coupling, switching regulators, and RF applications. Its low profile, high saturation current rating, and good heat dissipation properties make it an ideal choice for a wide range of applications. As it has a fixed inductance that cannot be changed after manufacture, it is important to select the correct inductor for the application in order to ensure optimum performance.
