Fixed inductors, also known as choke coils or coils, are passive electrical components consisting of a metal coil through which current flows. The inductance of a fixed inductor is constant with changes in current or frequency. The PE-0402CD8N2KTG is an example of a common fixed inductor.

The PE-0402CD8N2KTG is a 4-pin SMD inductor that provides high inductance giving it superior DC current characteristics. It has a dimension of 0402 and a rated idling current of 0.6A. With a thermoplastic material for the housing, the PE-0402CD8N2KTG has a minimum operating temperature of -40°C and a maximum temperature of +85°C. It is RoHS compliant with a direct plug-in mounting technology, which allows the inductor to be replaced without adjusting other components.

The application field of the PE-0402CD8N2KTG is wide, ranging from DC-DC converters, linear regulators, cell phone, communication units, and other electronic systems. Specifically, the PE-0402CD8N2KTG is used as a noise filter to reduce or prevent interference in electronic systems. It is also designed to suppress the electromagnetic field generated by large current flow in equipment or wiring.

The working principle of this fixed inductor is based on the concept of inductance, which states that when a current is applied to a metal wire or coil, it creates a surrounding magnetic field and an opposing voltage is generated. This voltage, also known as the back EMF or counter EMF, acts as a counterforce to the current, opposition. This opposition is proportional to the rate of change of the current. By increasing the rate of change of the current, a higher level of opposition is added, thus reducing the current level to the destination.

The PE-0402CD8N2KTG is designed to maintain this opposition at a consistent level while allowing a smooth flow of current in the desired direction. The inductor has a high resistive value compared to the total current, and can be adjusted by changing the rate of the current that passes through it. This allows the PE-0402CD8N2KTG to provide a reliable, low-noise voltage regulation system.

In conclusion, the PE-0402CD8N2KTG is a fixed inductor used in DC-DC converters, linear regulators, cell phones, communication units and other electronic systems. It is designed to reduce or prevent interference in such systems by creating a constant counterforce to a change in the current rate. This is achieved by creating an opposing magnetic field and generating an opposing voltage in response to the rate of the current. With its high resistance values and reliable, low-noise voltage regulation systems, the PE-0402CD8N2KTG is an ideal component for many applications.
