Introduction to Fixed Inductors

Fixed inductors are passive components that store energy magnetically within a coil of wire. The electric current passing through the wire creates a magnetic field, and the energy stored in this field can then be released in a controlled manner. Fixed inductors are used in a variety of applications requiring electric current or voltage control, such as circuit noise suppression, power supplies, and wireless applications.

The PM2110-1R2M-RC

The PM2110-1R2M-RC is a molded, through hole, radial leaded, 1.2µH ±5% inductor produced by Pulse Electronics. It is a molded ferrite device with an operating temperature range of -40°C to +125°C. The typical DC resistance of the PM2110-1R2M-RC is 7mΩ.

Applications of the PM2110-1R2M-RC

The PM2110-1R2M-RC is well-suited for use in high-brightness LED lighting, HVAC systems, consumer electronics, and automotive applications. As a controllable energy source, it can be used to regulate DC current or voltage, reduce circuit noise, and prevent electrical overload.

Working Principle of the PM2110-1R2M-RC

Fixed inductors work based on Faraday’s law of electromagnetic induction. In this law, when the current passing through a conductor changes, a magnetic field is created around the conductor. This magnetic field induces a voltage in the conductor, which then opposes the change in current. This opposition creates a stabilization of the current and voltage, which explains the benefit of fixed inductors in regulating current and voltage.The PM2110-1R2M-RC is composed of two windings of insulated copper wire wound around a ferrite core. As current passes through the core, a magnetic field is created which induces voltage in the two leads. The 1.2µH inductance rating of this particular device ensures proper regulation of AC and DC power for the desired application.

Conclusion

The PM2110-1R2M-RC is a 1.2µH ±5% molded, through hole, radial leaded, fixed inductor manufactured by Pulse Electronics and designed for a variety of applications. These applications include high-brightness LED lighting, HVAC systems, consumer electronics, and automotive applications. The PM2110-1R2M-RC operates on the principle of Faraday’s law of electromagnetic induction, using the magnetic field created by current passing through the insulated copper windings to induce a voltage in the leads and thus regulate AC and DC power.
