S1210-181G Fixed Inductors: Application Field and Working Principle

Fixed inductors are devices that are used for generating a magnetic field. They are made up of a coil of an insulated wire wrapped around a core of ferromagnetic material such as iron. When an alternating current (AC) is applied to the winding of the inductor, a flux is generated that links to the inductor itself and its surrounding air. This flux creates an induced current that is proportional to the amplitude of the applied voltage and frequency.

One of the best-known fixed inductors is the S1210-181G, which is a surface-mount inductor with a shielded structure. It is designed for use in general-purpose circuits and is typically used in television receivers and power supplies. The S1210-181G has a peak current rating of 1.2A and a self-resonance frequency of 139MHz. It also features a low inductance tolerance of ±10%.

Applications

The S1210-181G has a variety of applications. It is used in radio receivers to filter the radio signals, allowing only the desired frequencies to pass through. It is also used in power supplies to reduce the current disturbance caused by switching operations, preventing any power losses from the system. The S1210-181G is also used in television receivers to create efficiencies in the filtering of signals.

Working Principle

The S1210-181G fixed inductor works by inducing an electromagnetic field around the windings of the coil when a current is applied. This flux in the form of a magnetic field is proportional to the applied current, meaning that higher currents generate more flux. Since the inductance of the inductor is a function of the number of windings in the coil, the flux generated is also a function of the inductance.

When a sinusoidal voltage is applied to the winding, an alternating current flows through, generating an alternating flux around the windings of the core. As this current passes through the inductor, a voltage is also induced, which is proportional to the rate of change of flux. This induced voltage is known as the back EMF.

The magnitude of the back EMF is dependent on the inductance of the inductor, which can be adjusted by changing the number of windings in the coil. The S1210-181G inductor has a smart design that allows it to maintain an optimum operating ratio between the inductance and the peak current rating. This ensures that the inductor is able to supply a consistent amount of current even when subjected to varying loads.

Conclusion

The S1210-181G inductor is a highly accurate and versatile fixed inductor that is used in a wide range of applications. This device is able to generate a strong electromagnetic field that is proportional to the current applied, making it perfect for devices such as radio receivers, power supplies, and television receivers. The smart design also ensures that it can handle varying loads and maintain a consistent current output. Taking into account all of its unique features and advantages, the S1210-181G is an amazing example of the versatility of fixed inductors.
