Fixed Inductors

Inductors or coils are predominantly passive components that store electrical energy in the form of a magnetic field when electric currents flows within them. A fixed inductor is a component in which the inductance has a fixed value which is typically chosen according to a specific purpose. The HCMA1707-150-R is a general-purpose fixed inductor manufactured by Honewell International Co., Ltd., which is suitable for industrial, consumer, and automotive applications.

Basic Structure and Material of HCMA1707-150-R

The basic concept of an inductor is simply a coil of wire wound around an iron or ferrite core, which is driven by an electric current. The HCMA1707-150-R is a low profile, low cost fixed inductor with a 0.75 mm height and a 7 mm diameter. The core material is ferrite with a wire-wound construction. It uses a copper wire coil, which is magnetically shielded and has a painted case. The inductor is designed in a radial direction and is lead free in accordance with RoHS guidelines.

HCMA1707-150-R Application Field and Working Principle

The HCMA1707-150-R fixed inductor is suitable for a wide variety of power supplies, filters, and noise improvement circuits. It is also suitable for automotive applications such as power systems, charging circuits, alternators, and inverters. The working principle of the HCMA1707-150-R fixed inductor is based on electromagnetic induction. This principle states that when electric current flows through the inductor, a magnetic flux is generated and stored in the iron or ferrite core. This magnetic flux generates an electromotive force that opposes the change in current and as a result, the inductor resists changes in current. The HCMA1707-150-R has a rated inductance value of 1.5 µH and a rated DC current of 1.05 A, although it can handle up to 1.5 A for pulses of ≤50 ms at 20% duty cycle.

Conclusion

The HCMA1707-150-R fixed inductor is a low profile, low cost component that can be used in a variety of power supplies, filters, and noise improvement circuits. It is ideal for automotive applications such as power systems, charging circuits, alternators, and inverters. The working principle of this component is based on electromagnetic induction, which states that a magnetic flux is generated and stored in the core when electric current flows through the inductor, which generates an electromotive force that opposes changes in current. The HCMA1707-150-R has a rated inductance value of 1.5 µH and a rated DC current of 1.05 A, with a maximum current of 1.5 A for pulses of ≤50 ms at 20% duty cycle.
