The B82476A1684M000 also provides high inductance values and a wide range of inductance offering flexibility in selection. It is available in several sizes and shapes to fit different applications.

Advantages of B82476A1684M000

The B82476A1684M000 has some advantages that make it a preferred choice compared to other types of inductors:

• Low profile and lower DC resistance
• Higher power efficiency
• High frequency operations with low losses
• Superior voltage standing wave ratio (VSWR)
• High current carrying capacity

Working Principle of B82476A1684M000

The working principle of the B82476A1684M000 is based on Faraday’s law of electromagnetic induction which states that changing electrical current produces a magnetic field. In the case of fixed inductors, when an alternating current passes through its coils, it creates a circulating electric field which gives rise to a magnetic field. The varying magnetic flux generated by the electric field induces an electromotive force (EMF). This EMF works against the current producing a magnetic field. Thus, the induced EMF is proportional to the rate of change of the current, which is also known as the inductance. The B82476A1684M000 also follows Faraday’s law of electromagnetic induction as described earlier. The only difference is that it has a higher inductance than other types of inductors, which means it can store more energy. This makes the B82476A1684M000 more effective in applications such as power supplies and power electronics, where a higher level of stored energy is required.

Conclusion

The B82476A1684M000 fixed inductor is a robust and efficient component that is ideally suited for commercial and industrial applications such as power supplies, converters, and motion control. It has a high power density, low losses in high frequency operations, and a high current carrying capacity. Moreover, it follows the principle of electromagnetic induction and stores more energy than other types of inductors as it has a higher inductance value.
