Fixed inductors refer to a group of passive electronic components with inductance such as resistors, capacitors, and capacitors. The common inductors on the market include fixed coil inductors and variable coil inductors. The SP1210-122J is a fixed inductor. Its application field and working principle are introduced below.
Application Field of SP1210-122J
SP1210-122J is a fixed inductor widely used in various fields, including power supply circuits, filter circuits, communications, and consumer electronics. In power supply circuits, SP1210-122J can serve as an energy storage, filter out the common-mode interference, and reduce the amount of leakage current. In filter circuit, it can eliminate the interference caused by power supply, ground wires, and other difficulty to eliminate noise sources, thus improve the signal-to-noise ratio. In communication products, it can be used for the interstage matching filter and other functions, perform signal transmission by improving the signal quality. In consumer electronic products, such as digital cameras, mobile phones, and smart home appliances, SP1210-122J can reduce the EMI noise generated due to different switching frequencies.
Working Principle of SP1210-122J
The working principle of SP1210-122J is based on Faraday’s electromagnetic induction law. Its structure consists of a wound coilmade of an iron core and a magnetic wire of a certain diameter. When an alternating current is generated with a certain frequency, it will generate an induced electromotive force (EMF) in the coil. This EMF has a certain value, and the magnitude is related to the frequency and the number of turns of the coil. When the primary drive current passes through the coil, a magnetic field will be generated in the coil, so that both the left and right sides of the coil cut the magnetic field lines, inducing a certain EMF, thus resulting in inductance.
Conclusion
To summarize, SP1210-122J belongs to the category of fixed inductors, and the application covers a wide range. Overviewing its working principle, the SP1210-122J is under the law of Faraday’s electromagnetic induction. It passes an alternating current through a wound coil and then the coil cuts the magnetic field, resulting in inductance.
