Fixed inductors, commonly referred to as chokes, are devices constructed from a length of wire which is wound around a core or bobbin. The terminal connections are made to this winding and it forms a magnetic component that responds to an applied voltage. A fixed inductor is most typically used as an electrical filter which is used to reduce or prevent the effects of electronic noise on an electrical circuit. The CIGW201610GLR47MLE fixed inductor is a lead-free, RoHS compliant component which provides excellent performance in a variety of applications.

Application Fields

Fixed inductors are used in a variety of applications where current needs to be filtered or limited. This includes power supplies, motors, transformers, and even audio systems. In addition, these components are widely used in RF applications where high-frequency signals are present. The CIGW201610GLR47MLE fixed inductor offers excellent performance for all of these applications thanks to its large inductance (4.7mH ± 20%) and low DC resistance (0.73Ω ± 10%). The low DC resistance allows for minimal loss of power due to heating of the component.

Working Principle

The working principle of a fixed inductor is based on the concept of mutual inductance. When an alternating current (AC) passes through the inductor’s coil core, it creates a magnetic field. This magnetic field generates a current in the opposite direction, creating a feedback loop. This opposition to AC currents reduces the peak amplitude of the current and creates a filtering effect. Depending on the inductance of the component, the frequency range in which the filtering occurs will vary. The CIGW201610GLR47MLE fixed inductor offers excellent filtering characteristics up to several hundred MHz.

Conclusion

The CIGW201610GLR47MLE fixed inductor is an excellent choice for applications requiring high-quality filtering or current limiting. Its relatively low DC resistance allows for minimal power loss due to heating, while its high inductance allows it to filter frequencies up to several hundred MHz. This component is well suited for a variety of applications including power supplies, transformers, motors, audio systems, and RF applications.
