Fixed Inductors
Inductors are components which primarily store electrical energy in the form of a magnetic field when current passes through them. Fixed inductors, often referred to as "coils" or "chokes", are a type of inductor which consists of a wire wound into a specific shape and size in order to create a high inductance value with very low losses.The SP1210-332K is an example of a fixed inductor which is primarily used for power line filtering, and comes in a 10mm SMD package size. It has a rated inductance of 3.3µH, current rating of 1.2A and saturation current of 2.4A.Application Field
Fixed inductors, and particularly the SP1210-332K, are primarily used for power line filtering applications, as they help prevent electrical noise from reaching sensitive circuits. This is achieved by having the inductor act as an impedance between the power supply and the load, reducing the passage of noise signals on the power line, and thus improving the performance of the entire system.The SP1210-332K has a current rating of 1.2A and saturation current of 2.4A, making it suitable for higher power supply filters, such as power supplies used in home theater systems, and other devices.Working Principle
The basic working principle of a fixed inductor is that when a current passes through it, the resulting magnetic field will induce a voltage which will oppose the initial current. This is known as the "back e.m.f." (electromotive force) and is the primary reason why inductors are used for power line filtering.The SP1210-332K has a rated inductance of 3.3µH, meaning that it will oppose any changes in the current flowing through it. As the current increases, the back e.m.f. also increases, eventually reaching a level where it completely cancels out the initial current. This has the effect of "smoothing out" any rapid current changes, thus reducing unwanted electrical noise.Conclusion
The SP1210-332K is a fixed inductor which is primarily used for power line filtering applications. It has a rated inductance of 3.3µH, current rating of 1.2A and saturation current of 2.4A, making it suitable for higher power supply filters. The basic working principle of a fixed inductor is that when a current passes through it, the resulting magnetic field will induce a voltage which will oppose the initial current, thus reducing unwanted electrical noise.The specific data is subject to PDF, and the above content is for reference
