160-222FS

Fixed inductors are components that electrically act to resist the flow of current in a circuit. The most common type of fixed inductors is 160-222FS. This article will discuss 160-222FS application field and its working principle.

Application Field

160-222FS inductors are widely used in power, audio and radio frequency applications due to their fast and accurate response time. They are predominately used for storing and transferring energy in a circuit, which is why they are commonly employed in amplifier circuits and AC to DC power supply units. In addition, they can also be used for filtering, voltage regulation, and even energy transfer between highly sensitive electrical components.

Working Principle

160-222FS fixed inductors operate based on Faraday’s Law of Induction. This law states that when a conductor is placed in a varying magnetic field, an electromotive force (EMF) will be produced in the conductor. This EMF is proportional to the rate of change of magnetic flux. 160-222FS inductors work by using this EMF to produce a voltage drop across the inductor, thus limiting the current flow through the circuit.

The voltage drop depends on the frequency of the current being applied, the size of the inductor, and the amount of turns of wire in the windings. The higher the frequency, the higher the voltage drop. Similarly, the higher the number of turns in the inductor, the higher the voltage drop. The size of the bobbin also affects the voltage drop, where shorter bobbins will produce higher voltages than longer ones.

When an inductor experiences a sudden surge in current, the voltage across the inductor will go up as it needs to draw from its magnetic reservoir to cope with the surge. This will lead to an increase in the voltage drop across the inductor. As the current dissipates, the inductor begins to release its stored energy, and the voltage drop will slowly decline. This phenomenon is known as inductor ringing or transient response.

Conclusion

The 160-222FS fixed inductor is an important component in power, audio and radio frequency applications due to its accurate and fast response. Its operation is based on Faraday\'s law of induction. The voltage drop across the inductor is affected by the frequency of the current being applied, inductor size and number of turns of wire in the windings. When a surge in current is experienced, the inductor will \'ring\' as it stores and releases energy.
