Fixed inductors is a type of electrical device which is used to store energy in the electric and magnetic fields. The TO1608-220M inductor, in particular, is a relatively small device that can be used in a wide variety of applications. In this article, we will discuss the application field and working principle of the TO1608-220M fixed inductor.

Application field of TO1608-220M Fixed Inductor

The TO1608-220M fixed inductor is most commonly used in small electronic applications on the PCB board. These inductors are not intended for high current applications, but can be used when considerable current may be involved in a circuit. It is most typically used as an AC power filter, noise filter, or for DC-DC converters.

In addition, this type of inductor is often used in LED dimming circuits. As LEDs require a current to be dimmed, the inductor can act as a variable resistor. This allows a range of current to be supplied to the LED array, enabling the desired degree of dimming.

Fixed inductors can also be used in boost converters and charger circuits. These circuits are used to raise the voltage of a power supply and charge the battery respectively. Both these processes require the presence of a fixed inductor.

Working principle of TO1608-220M Fixed Inductor

A fixed inductor consists of two coils of wire wrapped in a core material, typically ferrite or iron. The coils are configured in such a way that a current passing through one of the coils will induce an electromagnetic field in the second coil.

When an alternating current is passed through the inductor, the alternating magnetic field induces an electrical voltage in the second coil. This is due to the nature of electromagnetic induction, whereby a changing magnetic field in one coil induces an electromotive force (EMF) in the second coil.

Furthermore, the inductance value of the inductor is determined by the size of the coils and the permeability of the core material. Larger coils and higher core permeability values result in greater inductance, while smaller coils and lower permeability values result in lower inductance values.

Conclusion

The TO1608-220M fixed inductor is a type of electrical device mainly used in small electronic applications. Its application field includes AC power filters, noise filters, LED dimming circuits, boost converters, and charging circuits. It works based on the principle of electromagnetic induction, whereby an alternating current passing through one coil induces a voltage in the second coil due to the changing magnetic field.
