Fixed Inductors

Inductors are electronic components used in a vast array of applications from power supplies to filtering and sensing. Fixed inductors (or non-tunable inductors) are an especially important component in electrical and electronic circuits, as they are used in many applications from basic power supplies to complex switching circuits. The SPD125-153M fixed inductor is a popular component in electrical and electronic designs, due to its durable construction and impressive range of features.

SPD125-153M Application Field

The SPD125-153M is a surface mount fixed inductor for use in general purpose applications. It is well suited for SMPS, PFC, and filters. The inductor has a relatively small footprint for its rated power, making it ideal for compact circuits where a precise inductance is required. The component is also well suited for DC to DC conversion, as well as power factor correction and other applications that require an inductor with a high saturation rating. The large variety of packages available with this inductor ensures it can be used in a wide range of applications.

SPD125-153M Working Principle

The SPD125-153M consists of a core material (such as ferrite), along with coiled copper wire wrapped around it. When an electrical current is applied to the inductor, the core material reacts to create an electromagnetic field. This field acts to resist a change in the current, and thus the inductance increases as the current increases. As the current changes, the electromagnetic field will also change, resulting in a change in the inductance.

The actual inductance of the SPD125-153M is determined by the core material, the number of turns in the coil, and the diameter of the copper wire. Inductance values can range from 1uH to 5uH, though values as high as 200uH can be achieved with special configurations. As the inductor has a relatively low DC resistance, it can handle higher currents with minimal power loss.

Conclusion

The SPD125-153M fixed inductor is a versatile and durable component capable of withstanding high voltages and currents. It is a popular choice for use in many different electrical and electronic applications, due to its impressive range of features. The working principle behind the component is simple: when current is applied, the core material creates a magnetic field which can either increase or decrease the inductance, depending on the current.
