Fixed Inductors

Inductors are electrical devices which store energy in a magnetic field created by the flow of electric current. The two main types of inductors are based on their construction: fixed inductors and variable inductors. Fixed inductors are usually made from coiled wire; they contain stationary windings that do not have adjustable features. The PL9407 is a fixed inductor, which is used in a variety of applications. This article will discuss the application field and working principle of the PL9407.

Application Field

The PL9407 is a shielded, axial-lead fixed inductor that is ideal for space-constrained applications. It is commonly used in power management, devices such as DC/DC converters and switching power supplies, as well as high-frequency radio equipment. This device is also popular in automotive electronics, medical electronics, telecommunication equipment, and military applications.

Working Principle

As with other inductors, the PL9407 has windings that create a magnetic field when current passes through them. This magnetic field stores energy, which then passes back out of the inductor, delaying the current flow and extracting power in the process. This stored energy is released into the circuit in the form of a voltage pulse. The magnitude of the voltage pulse depends on the number of turns in the winding and is proportional to the number of turns squared.

The internal construction of the PL9407 consists of a high-saturation zinc-ferrite core and enamel copper wire windings. Its performance is dependent on the number of turns, as well as its physical size and construction. The overall size of the device is also an important consideration, as its physical dimensions determine where it can be used in circuits.

Conclusion

The PL9407 fixed inductor is a useful device which can be used in a variety of applications, such as power management, DC/DC converters, radio equipment, automotive electronics, medical electronics, telecommunication equipment, and military applications. Its working principle involves creating a magnetic field which stores energy and then releases it in the form of a voltage pulse. The device is small and compact, making it ideal for space-constrained applications.
