Fixed Inductors

Inductors, also known as coil, chokes, or reactors, are passive two-terminal electrical components which resist changes in electric current passing through them. The low-frequency, frequency-dependent opposition to current passing through them is called inductance, which is measured in Henry (H).The B1047AS-8R2N=P3 is an example of a fixed inductor. It is a very small, surface-mounted inductor with extremely low DC resistance, suitable for a wide range of applications.

Applications

The B1047AS-8R2N=P3 inductor is a cost-effective solution for a wide range of applications such as:

• Power supply decoupling.
• Filter circuits.
• RF interference suppression.
• EMI suppression.
• High switching speeds.
• Switching power supplies.
• Automotive electronics.
• Voltage regulators.

Working Principle

The basic principle behind an inductor is Faraday’s law of induction, which states that changing the current in a circuit induces an electromotive force (EMF) in a closed circuit. The B1047AS-8R2N=P3 inductor works by forming a closed circuit. When current is passed through the inductor, the magnetic field it creates induces an EMF proportional to the rate of change of current. This EMF opposes the current, thus producing a resistance to the flow of current. This resistance is called inductance, and is constant after the inductor has been properly sealed and stored. Different types of inductors have different inductance values depending on their physical characteristics and on the level of current passing through them.

Conclusion

The B1047AS-8R2N=P3 is a fixed inductor which is extremely small and cost-effective. It is designed for a wide range of applications, such as power supply decoupling, filter circuits, RF interference suppression, EMI suppression, high switching speeds, switching power supplies, automotive electronics, and voltage regulators. The indcuctance of the B1047AS-8R2N=P3 is constant regardless of the level of current passing through it, and is generated according to the Faraday’s law of induction.
