Fixed inductors are electrical components that store energy in a magnetic field through the generation of a magnetic flux around a conductor. PE-0402CD7N5KTG is an example of such a component. While inductors have been around since the late 1800s, the invention of these components has revolutionized the electronics industry and enabled major advancements in power management.

PE-0402CD7N5KTG is a miniature wire wound chip inductor with a 0.47μH inductance in a 0402 footprint; it has a low profile, 7.5 mm max. height, and it can operate from -55°C to 125°C.

The main application for PE-0402CD7N5KTG is in switching power supplies. These inductors are an ideal storage facility for short-term energy which is used to smooth out the DC current waveform. By storing and releasing energy into the load, power supply designs can reduce drop out voltages and provide cleaner current flow. An example is the well-known “ripple rejection” effect which is a measure of the degree to which an inductor can shape the current waveform.

The working principle of the PE-0402CD7N5KTG is that it is an active reactor that generates an electromagnetic force when an electrical current flows through it. This force can be used to refine AC currents and reduce high frequency components. Generally, the active voltage and current around the inductor are balanced, forming a sort of equilibrium between the two fields. The inductor can act as a resistor, allowing a certain amount of current to flow through it depending on the design of the component.

PE-0402CD7N5KTG is also used in situations where DC current needs to be filtered out. In this case, there no real “storage” of energy, as the inductor simply works as an impedance to the DC current. The inductance of the component dictates the amount of current that can flow through it, which helps maintain a consistent voltage level in the presence of varying DC current.

Overall, PE-0402CD7N5KTG is a versatile and reliable inductor that can be used in a variety of applications. Its low profile and temperature range make it well-suited for modern electronics, and its ability to store and refine energy makes it a perfect choice for switching power supplies.
