Fixed Inductors

Inductors are passive devices used in electronic circuits to induce a current in response to the presence of an electric field. Fixed Inductors are components which have been designed to feature a chosen inductance value that is intended to be kept constant in order for the same response of the current to be achieved for each application. An example of a fixed inductor is the SCPH73-271, which shows excellent performance in inverters, DC/DC converters, and smoothing circuits, among other applications.

SCPH73-271 Application Field

The SCPH73-271 type fixed inductor is small in size and can be used for various types of digital and analog circuit boards. Its main application is in DC/DC converters because of its high oscillation cycle and power efficiency for high frequency duties. In such cases, its role is to convert a high-voltage DC power supply into a safe low-voltage DC power supply.

In other applications, such as inverters, the SCPH73-271 can be used to convert a DC voltage into an alternating current. This is done by oscillating rectifiers and operated at high frequency. In addition, the SCPH73-271 can also be used in smoothing circuits where it effectively controls the ripple voltage caused by input AC power supplies, to maintain the desired voltage level.

SCPH73-271 Working Principle

An inductor works by using an electromagnetic field to store energy within a magnetic circuit. The inductor is made of a coil of insulated wire, usually made of copper and wrapped around a core, which can be composed of magnetic material (ferrite core) or iron (iron core), to increase the magnetic field. The amount of induced current depends on the inductor’s inductance.

The SCPH73-271 features an adjustable inductance which can be easily adjusted, using a variable resistor provided in each of the inductor. It also includes a built-in shield which prevents EMI interference. When the SCPH73-271 is used along with other components, it can reduce the voltage fluctuation caused by the input AC power supply and, therefore, achieved a stabilizing effect for the digital and analog board.

In sum, the SCPH73-271 is a fixed inductor that can be applied in various circuit designs due to its small size, adjustable inductance and built-in shield which makes it efficient for stabilizing AC power sources. Therefore, the SCPH73-271 is an ideal component for the use in many digital and analog boards.
