Fixed Inductors

Inductors are electronic components designed to store energy in the form of a magnetic field. Fixed inductors are components that have no adjustable features such as tap points, variable cores, or core shunts. The SPD125R-564M is a type of fixed inductor that can be used in many applications. The following sections will provide an overview of the SPD125R-564M, its application fields, and how it works.

Overview of SPD125R-564M

The SPD125R-564M is a surface-mount fixed inductor, meaning it is designed for use on the surface of a printed circuit board (PCB). The component is one of the many varieties of SMT components that are commonplace in modern electrical engineering. The inductor measures 5.6 x 4.2 millimeters, so it can fit almost any size printed circuit board. It has an inductance value of 1.25uH (microhenries).

Applications of SPD125R-564M

The SPD125R-564M can be used in a wide variety of applications. It is primarily used in filter circuits to reduce interference and noise caused by other components in the system. It can also be used in input/output stages of amplifier and signal conditioning circuits. It is also commonly used in switching power supplies, resonant circuits, time-delay circuits, and voltage regulators.

Working Principle of SPD125R-564M

The SPD125R-564M works on the principle of mutual inductance. Mutual inductance is the phenomenon that occurs when two inductors are placed close together. When a current is passed through the first coil, the magnetic field that it produces will induce a current in the second coil. The magnitude of the induced current will be proportional to the number of turns in the second coil, and inversely proportional to the distance between the coils. The SPD125R-564M produces a magnetic field when a current is passed through it, which then induces a current in the second inductor. The amount of current induced is determined by the number of turns in the coil, and the type of core material used. The core material affects the shape of the magnetic field, and thus the magnitude of the induced current.

Conclusion

The SPD125R-564M is a type of fixed inductor commonly used in filter circuits, amplifier and signal conditioning circuits, switching power supplies, resonant circuits, time-delay circuits, and voltage regulators. It works on the principle of mutual inductance, whereby a current is passed through one coil, and a magnetic field is created that induces a current in a second coil. The SPD125R-564M is a popular choice due to its small size and high performance capabilities.
