Fixed Inductors: LQM31PN2R2M00L Application Field and Working Principle

LQM31PN2R2M00L is a fixed inductor which belongs to a line of components called "fixed inductors," also known as chokes. This specific product is manufactured by Murata Electronics, one of the world’s leading manufacturers of electronic components. This inductor can be used in circuit designs where inductance values are required to be regulated and its working principle is based on the principle of the transformer.

Purpose of Fixed Inductors

A fixed inductor is an electronic component that utilizes a coil of wire to introduce inductance into the circuit. This inductance is used for a variety of applications, including: filtering high-frequency noise, impedance matching, and power-supply regulation. In addition, fixed inductors are also used in circuits to control alternating current circuits by blocking direct current interference, and to provide magnetic shielding for sensitive circuits.

Working Principle of the LQM31PN2R2M00L

The working principle of the LQM31PN2R2M00L is based on the transformer principle. A transformer works to transfer electrical energy from one circuit to another by virtue of a changing magnetic fields created in a coil. When a voltage is applied to the primary winding of the LQM31PN2R2M00L, an alternating magnetic field is generated, the flux of which cuts the secondary winding. This in turn induces a voltage in the secondary winding, which is the output voltage of the fixed inductor.

Conclusion

The LQM31PN2R2M00L is a fixed inductor from Murata Electronics which can be used in numerous applications. It has an inductance value of 2.2 μH, a rated current of 3.4A, and a Q factor of 10.6. It is based on the working principle of the transformer and employs an oxide-coated aluminum nickel-zinc magnet wire for its construction. The LQM31PN2R2M00L is an excellent choice for applications such as filtering, matching, shielding, and regulating power-supplies.
