Fixed Inductors

A fixed inductor, is an electronic component that stores energy in a magnetic field. It’s a passive electrical component that’s used to limit the flow of electric current in an electronic circuit. Generally, it’s a two terminal device and has a coil of wire that’s wound around a core material.

LQW31HNR10J03L application field and working principle

The LQW31HNR10J03L is a fixed inductor made by Murata. It’s a 0402SMD inductor with a coil resistance (DCR) of 0.28 Ohm. It’s designed for surface mount applications and is made with high temperature range substrates. It has a polyimide insulation coating for protection.

The LQW31HNR10J03L’s core material is typically made of Ferrite which is a magnetic material that helps facilitate the transfer of energy between the two terminals. It has an inductance value ranging from 0.75 to 3.0nH. The LQW31HNR10J03L also has relatively low DCR which improves current transfer and helps to reduce power loss.

The LQW31HNR10J03L can be used in a number of applications including power conversion, power management, and voltage regulation. It’s specifically designed for use in high frequency switching power converters, voltage step-down voltage regulators, motor control, and lighting control systems. The LQW31HNR10J03L operates based on Faraday’s Law, which states that a changing magnetic field produces an induced current in a coil due to the varying electric field.

The amount of induced current is proportional to the rate of change of the magnetic flux linkage. The induced current can be used to power or regulate other components in the circuit. The electro-magnetic design of the LQW31HNR10J03L helps to minimize the flux leakage so that the inductor can effectively store and transfer energy within the circuit.

In conclusion, the LQW31HNR10J03L is a fixed inductor made by Murata that’s designed for use in high frequency switching power converters, voltage step-down voltage regulators, motor control, and lighting control systems. It’s composed of a coil of wire wrapped around a ferrite core material, and it operates based on Faraday’s Law. It has a relatively low DCR and a high insulation rating, which helps to maximize its efficiency and reduce power loss.
