Fixed Inductors

Inductors are elements which store energy in the form of a magnetic field in a wiring circuit. The most common type is a fixed inductor, which is a passive two-terminal electrical component used to store energy in a magnetic field. It is usually made of a metallic conductor; either a large coil of wire wound around a ferrite core, or a printed circuit board (PCB) containing a spiral etched copper pattern. Fixed inductors are widely used in circuit design, particularly in power supplies, switches, and converters.

156L Application Field

156L is an ultra-low-resistance fixed inductor that has become popular for its ability to provide high-current operation. This inductor is used to provide filtering or transient suppression in high-power applications. It is typically used in applications requiring power-conversion circuits, motor control, AC/DC converters, high-speed switching, switch-mode power supplies (SMPS), power factor correction (PFC) and voltage-mode controllers (VMCs).

156L Working Principle

The 156L inductor is a compact component that uses an organic core material to reduce resistance and produce an inherently low-resistance-to-inductance ratio. This produces exceptional efficiency over a wide temperature range and can be used to achieve tight tolerance on power distribution and signal stability. Through the use of its organic core material, the 156L also provides excellent temperature stability for improved circuit performance and reliability.

The 156L inductor is designed with a dual construction, consisting of a copper spiral wound around a ferrite core. The core provides the magnetic flux which produces the electromagnetic field, and the copper winding on top is the electrical conductor. The copper spiral serves to minimize the electric field interference which can occur between the magnetic flux and the copper winding. This allows the 156L inductor to achieve improved attenuation and compliance with stringent requirements.

The 156L inductor also incorporates a controlled manufacturing process that ensures high reliability and consistent performance. Its high power-handling levels and impressive heat dissipation capabilities make it an ideal choice for many high-current applications.

Conclusion

The 156L inductor is an ultra-low-resistance fixed inductor that is particularly suitable for high-current applications like power-conversion, motor control, AC/DC converters, SMPS, PFC and VMCs. Through its organic core material and controlled manufacturing process, it provides excellent efficiency and temperature stability for improved circuit performance and reliability. With its high power handling levels and impressive heat dissipation capabilities, the 156L inductor is an ideal choice for many high-current applications.
