Fixed inductors, also known as inductors, are passive two-terminal electrical components consisting of a wire conductor wound as a coil creating a magnetic field when current flows. The 6721 is a wide range inductor that is packaged with a tight fitting bobbin available in sizes from 7mm to 45mm. Power inductor type 6721 is constructed by winding an insulated wire around a ferrite core and an iron core and is used in a variety of applications such as power factor correction, voltage transient filtering, differential-mode filtering, motor drive, electronic lighting, and renewable energy.

Applications

The 6721 inductor is suitable for a wide range of applications due to its size, power rating, and wide current range. The most common application for this inductor is in power factor correction for AC/DC power supplies. This inductor helps to improve the performance of AC/DC power supplies by increasing the power factor of the system, which reduces power consumption and increases efficiency. Additionally, the 6721 can be used for voltage transients filtering, differential-mode filtering, motor drive, electronic lighting, and renewable energy.

Working Principle

The basic working principle of the 6721 inductor is based on electromagnetic induction. When a direct current (DC) flows through the inductor, it creates a magnetic field around the inductor. This magnetic field then induces a voltage in the inductor that is proportional to the rate of change of the current. This voltage is opposite to the applied voltage of the inductor, which causes the inductor to store energy. The inductor will then increase the effective impedance of the circuit, causing the current to decrease. This decrease in current reduces power consumption, while still allowing for an appropriate voltage drop.

The 6721 inductor also works as a differential filter, reducing the amount of noise passed from the signal source to the load. This is done by filtering out higher frequency components in the signal, which can cause distortion in the signal if not filtered. Additionally, the inductor helps to smooth out power supply ramps and reduce the “ringing” of a power supply.

Conclusion

The 6721 is a versatile inductor with a wide range of applications due to its size, power rating, and wide current range. Its primary use is in power factor correction for AC/DC power supplies, to reduce power consumption and increase efficiency. Additionally, the 6721 can also be used for voltage transients filtering, differential-mode filtering, motor drive, electronic lighting, and renewable energy. The inductor works by creating a magnetic field that induces a voltage in the inductor, which is opposite to the applied voltage and reduces power consumption. This decrease in power consumption allows for an appropriate voltage drop and also works as a differential filter, reducing the amount of noise passed from the signal source to the load.
