Fixed Inductors

Introduction

A fixed inductor, also known as a choke coil or simply a choke, is an electrical component used to impede the flow of alternating current (AC). It does this by creating a magnetic field in response to a current passing through it, storing the energy in the form of magnetic flux. Fixed inductors are widely used in both DC and AC applications.

3094-103KS Application Field

The 3094-103KS fixed inductor is a high-frequency, low-inductance component that works well in a variety of applications. It is most commonly used in switching power supplies, flyback converters, and other higher-frequency power supplies. Its small size and low inductance value make it the ideal device for applications that require a high degree of electromagnetic compatibility (EMC).

3094-103KS Working Principle

The working principle of the 3094-103KS is very simple. When a current passes through the inductor, a magnetic flux is generated which opposes the flow of current. This produces inductance. The higher the current passing through the inductor, the greater the flux and the resulting inductance. The inductance increases as the frequency of the current increases, as the rate of flux generation is dependent on frequency.The 3094-103KS has a maximum current rating of 150mA, with a maximum inductance of 0.058mH. It is constructed of a ceramic coil body and core, with a copper winding. The inductance value also depends on the number of turns present on the coil, and the overall size of the coil.

Conclusion

Fixed inductors play a vital role in many electrical and electronic applications, providing the necessary inductance to reduce the effect of currents. The 3094-103KS is a high-frequency, low-inductance component suitable for a range of applications. Its small size and low inductance value make it an ideal choice for those requiring higher levels of electromagnetic compatibility. The 3094-103KS is constructed of a ceramic coil body and core, with a copper winding. The inductance value depends on the number of turns of the coil, and its overall size.
