Fixed Inductors

Fixed inductors, often shortened as chokes, are passive electrical components that are used to store energy in the form of a magnetic field when current passes through them. A common application of fixed inductors is to filter out high-frequency interference in power supplies for electronic systems. One of the most popular examples of fixed inductors is the LQH43NN100J03L.

The LQH43NN100J03L is a fixed inductor with a relatively small package size that is designed for easy mounting and minimal clearance. Its rated inductance value of 100 microhenrys (uH) and rated current of 1.4 ampere (A) make it highly suitable for mobile device power system filter component applications. Its small package size also makes it suitable for devices with excellent system level performance.

Application Field

The LQH43NN100J03L inductor is commonly used in mobile device power systems, especially ones with excellent system level performance. It is available as either a vertical or horizontal mounted device and can easily be mounted in small devices such as smartphones and handhelds. The inductor is also highly suitable for other applications such as power-line and DC-DC converter filtering, radio noise filtering, and audio signal filtering.

Working Principle

The LQH43NN100J03L works according to the formula for an inductor: 6.28 x L x I = ?, where L is the inductance value (in Henries) and I is the current in amps.

The inductor works by creating and storing a magnetic field when current passes through it. The higher the current flow, the stronger the magnetic field will be. This field then opposes any changes in current flow, induces a counter emf in the external circuit, and limits the peak current flow. This makes it the ideal choice for power line and noise filtering applications.

In addition, the LQH43NN100J03L has a low temperature coefficient, meaning that its inductance will remain relatively consistent over a range of temperatures. This is an especially important factor to consider when using inductors in high-temperature applications such as portable electronics.

Conclusion

The LQH43NN100J03L inductor is a popular fixed inductor that is commonly used in mobile device power systems and other applications such as power line and noise filtering. Its rated inductance value of 100 uH and rated current of 1.4 A make it highly suitable for its intended applications, while its small package size and temperature stability make it an ideal choice for high-temperature applications.
