Fixed Inductors

A fixed inductor, also known as a discrete inductor, is an electrical component primarily used to store energy in a magnetic field and prevent the flow of direct current (DC) in an alternating current (AC) circuit. Fixed inductors are usually composed of an iron core wrapped in a coil of insulated copper wire. There are many different types of fixed inductors, depending on the purpose. Here, we will focus on the fixed inductor LQW04AN5N1D00D and its application field and working principle.

Features and Applications

The fixed inductor LQW04AN5N1D00D is part of the LQW Series of surface-mount inductors. It is an option-packed inductor that is capable of performing over a wide frequency range. It has an excellent low-frequency performance at high current and low-temperature coefficient of inductance, which makes it suitable for applications such as AC-DC and DC-DC converters, power supplies, and current transformers. It is also used in a variety of other applications including RF signal switching, FM radios, and AM receivers. Additionally, it is RoHS compliant, making it an ideal choice for environmentally friendly applications.

Working Principle

Fixed inductors work on the basis of the principles of magnetic induction. When current flows through a wire, it produces a magnetic field, and if this wire is then wound around an iron core, the magnetic field will increase and be constrained to the inductor. As the current varies, the magnetic field strength will fluctuate, inducing an electromotive force in the circuit. This electromotive force produces a reverse current that opposes the flow of the original current, thus limiting its speed or regulating its current level.

When the current passes through the coil, the direction of the field changes, creating a new electromagnetic field and inducing a new current. This creates an opposition and a resulting back-EMF between the terminals of the inductor. The back-EMF is proportional to the rate of change of the current, which is then used to regulate the flow of the current. This phenomenon is known as self-induction and is used in a variety of applications to control currents.

Benefits

Fixed inductors provide a number of benefits for AC-DC and DC-DC converters, power supplies, and other applications. The use of fixed inductors eliminates the need for bulky transformers, reducing the overall size and cost of a system. They are also typically more efficient than other inductors due to their lower losses. Additionally, fixed inductors do not require regular maintenance or calibration, so they have a longer lifespan than other inductors.

Fixed inductors can also provide a high degree of electromagnetic interference (EMI) suppression, and they are capable of filtering out high-frequency noise. This makes them ideal for use in systems that require low-noise performance. Furthermore, fixed inductors can be easily soldered and mounted onto printed circuit boards, making them suitable for a wide range of applications.

Conclusion

In conclusion, the fixed inductor LQW04AN5N1D00D is a reliable and versatile surface-mount inductor that can be used effectively in a variety of applications. It has an excellent low-frequency performance at high current and low-temperature coefficient of inductance, and its ability to provide high EMI suppression makes it a great choice for applications where low-noise performance is required. The LQW04AN5N1D00D is also RoHS compliant and easy to solder and mount, making it an ideal choice for environmentally friendly applications. Overall, the LQW04AN5N1D00D is an excellent choice for a wide range of applications that require reliable inductors.
