Fixed inductors are electrical components with a single inductor winding. Inductors are commonly used to increase the current in output signals, filter noise, or store energy. They work by producing a magnetic field in a conductor when current passes through it. ER1840-105JM, a member of the ER series fixed inductor family from Panasonic, is specifically designed for high frequency applications.

This inductor has an inductance of 1.05uH and a quality factor of 30. It has low DC resistance and is stable up to 5GHz. It features a high insulation resistance, low dielectric loss, and high self-resonance. It is also temperature compensated and compatible with automated assembly processes.

The ER1840-105JM has various applications, primarily in high frequency mobile phones, cellular base stations, and other radio frequency wireless devices. It can also be used in power supplies, battery-powered devices, and electric tools.

The working principle of this inductor is based on Faraday\'s Law, which states that the rate of an induced EMF in a conductor circuit is proportional to the rate of change of the magnetic flux. This flux is generated by taking an alternating current and passing it through the inductor\'s winding. As the current passes through the winding, it creates a magnetic field which in turn produces an opposing voltage, which is equivalent to inductance. The frequency of this induced voltage depends on the frequency of the current. This voltage decrease is used to reduce the output voltage from the inductor.

The ER1840-105JM works by using a 1.05uH inductance combined with a quality factor of 30, helping to reduce the output voltage when an AC current passes through it. This allows it to filter out noise from audio signals and can be used to smooth out voltage spikes in power supplies.

The ER1840-105JM is a versatile component that can be used in a variety of high-frequency applications. Its low DC resistance and high insulation resistance make it suitable for use in power supplies, battery-powered devices, and electric tools. It can also be used to filter out noise from audio signals and can be used to smoothen out voltage spikes in power supplies.
