Fixed Inductors are components important to the functioning of a variety of electrical and electronic circuits. The TYS4012220M-10 is a type of fixed inductor manufactured by TDK corporation. This article will discuss the application fields and working principles of this particular product.

General Description

The TYS4012220M-10 is a radial-leaded, low-profile, high current Inductor with two terminals. It features a ferrite core as well as an enamel-coated wire for superior performance during high-frequency and short-circuit loading. This inductor is an SMD type, and is RoHS compliant. The typical inductance value of this product is 22µH, with a rated DC current of 6.8A.

Applications

The TYS4012220M-10 is a suitable choice for RFID circuit designs, infrared communications, inductors for switching regulators, high speed signal processing, and input filtering purposes. It is also good for DC-DC converter circuits, and for providing a passive bypassing filter between the input and output of sampling circuits. This device can also be used in anti-aliasing and notch filtering circuits.

Working Principle

A fixed inductor works by allowing a current to pass through its windings, creating a magnetic field around the inductor. This field then acts as a resistor to changes in the current, which in turn allows for the desired inductance value. This inductance value is determined by a combination of the core material, the number of turns, and the geometry of the winding process.

When a DC current is passed through the windings of the TYS4012220M-10 fixed inductor, it will create a magnetic field around the inductor, and also generate a voltage of approximately two times the current. The induced voltage and impedance created due to the inductor\'s construction will then limit the current, thus providing the necessary inductance value.

Conclusion

The TYS4012220M-10 is a high-current SMD fixed inductor that is suitable for a variety of applications; including RFID, IR communication, switching regulator, DC-DC converter circuits, input filtering, notch filtering, and anti-aliasing circuits. Its working principle is based on the field generated by the inductor windings, providing the necessary inductance to the circuit.
