Fixed Inductors

Fixed inductors refer to electronic components that use the principle of inductance to achieve the purpose of storing energy. They are widely used in the circuit to realize signal coupling, noise suppression and frequency filtering. SP1210-152H is a kind of small and high-frequency fixed inductor.

Application Field of SP1210-152H

SP1210-152H is mostly used for signal coupling, noise suppression or frequency filtering in small electronic equipment such as Notebook Bluetooth, printer, Set-top box, etc. It\'s not only a power attenuator in high frequency signal channel, but also can be used to reduce the differential and common-mode interference between insertion and RF environment.

Working Principle of SP1210-152H

Fixed inductors use the principle of inductance to store energy. The principle is that the current passing through a coil generates an induced electromotive force (EMF), as long as the primary coil winding current changes, and the induced electromotive force is proportional to the time change rate of the primary coil current, and then the secondary coil induces the current. Based on this principle, SP1210-152H can realize the signal coupling, noise suppression and frequency filtering through the way of bridge connection of four wire coil.

SP1210-152H can work effectively in high frequency (≥1 MHz) with low loss. Usually, when a certain rated current flows through one of its two ends, an electromagnetism field is generated around the coil, making the inductor generates the inductance reactance, so that the current can be limited.

Conclusion

SP1210-152H is a kind of small and high-frequency fixed inductor. It has a wide range of applications, including signal coupling, noise suppression and frequency filtering in small electronic equipment such as Notebook Bluetooth, printer, Set-top box, etc. It works effectively in high frequency (≥1 MHz) environment. It uses the principle of inductance to store energy, and the principle is that the current passing through a coil generates an induced electromotive force (EMF).
