Fixed Inductors

An inductor, also known as a coil, choke, or reactor, is an electrical component used to store energy in a magnetic field, resisting a change in electrical current in a circuit. Inductors come in many shapes and sizes, and play an important role in many electronic applications, especially in critical power supply circuits.

9406R-04 - Application Field and Working Principle

The 9406R-04 fixed inductor is an ideal component for a wide range of applications including, medical electronics, industrial control, instrumentation, and power electronics. It features an operating temperature range of -40 to +105 degrees, a max voltage of 220V, and a 6.3A current rating. The 9406R-04 is a cylindrical inductor made of a ferrite core and an enamel-coated copper wire winding. The specifications and dimensionless structure make it very suitable for mounting on PC boards.

Working Principle

The operating principle of the 9406R-04 fixed inductor is relatively simple. When an alternating current is passed through it, it stores energy in its magnetic field. This magnetic field will then resist any changes in the current, effectively limiting any increases or decreases. The inductance of the 9406R-04 inductor is related to the turns ratio, the size of the copper wire, and the size of the ferrite core.

The 9406R-04 inductor is also available in different sizes with varying inductance values. The inductance values range from 470uH to 10mH (milli-henry). The greater the inductance, the higher the ac resistance. This property can be beneficial in several applications, including those which require low noise in audio equipment. The sharpness of the resonance frequency of the inductor also depends on the parameters of the device, such as the inductance.

In addition, the 9406R-04 fixed inductor is also suitable for use in switched mode power supplies (SMPS) and power line filters. It can help to reduce high frequency spikes and noise in these applications. Furthermore, its high temperature resistant properties make it suitable for applications in harsh environments.

Conclusion

The 9406R-04 fixed inductor is a widely used component in various applications. Its simple operating principle makes it a desirable component for power supply and noise reduction applications. Its high temperature resistance also allows it to be used in harsh environments. With its various sizes and inductance values, the 9406R-04 fixed inductor is a great choice for any application.
