Fixed Inductors Overview

Fixed inductors are electronic components that are widely used in many electronic applications. They are most often used to provide a constant current to an electronic circuit, but can also be used to reduce noise, control filters, and stabilize signals. A fixed inductor is essentially a coil of wire that stores electrical energy, and redirects it in a specific way.

MS75085-4RU Application Field and Working Principle

The MS75085-4RU is a 4-inch (22 mm) dia. medium-power pot core inductor. It is suitable for applications such as AC and DC power circuits, switch mode power supplies, SMPS, charge pumps, DC-DC converters, and multiple winding structures. This product is optimized for medium power applications, where size and cost are important factors. The product features high-temperature resistance and improved saturation performance due to its amorphous core.

The MS75085-4RU is designed with a pot core structure, which essentially consists of two kraft paper and ferrite cores, with the coil wrapped around them. This design allows for a wide range of inductance values, and significantly improves inductor stability. The pot core also allows for higher saturation performance (i.e. it can handle higher current levels before saturating).

The MS75085-4RU is a multi-winding structure designed to provide strong inductance and high current handling capacity. It consists of one primary winding and one or more secondary windings. The primary winding is made of enameled copper wire and is used to supply the rated current. The secondary winding is made of non-magnetic litz wire and is used to “step down” the voltage and current supplied to the circuit.

The MS75085-4RU\'s working principle is based on the principle of electromagnetic induction, which states that a changing magnetic field will induce an electric current in a coil of wire. When an alternating electric current is applied to the primary winding of the inductor, a varying magnetic field is created which induces an electric current in the secondary windings of the inductor.

This induced current is then supplied to the circuit, allowing for a controlled flow of electrical energy. The inductor helps to reduce noise and filter out some of the unwanted RF signals, helping to improve the integrity and stability of the circuit. This enables it to be used in higher power applications where noise levels and circuit stability are critical considerations.

Conclusion

The MS75085-4RU is a 4-inch (22 mm) dia. medium-power pot core inductor designed for medium power applications. It features a high-temperature resistant core and improved saturation performance, making it suitable for numerous applications. The working principle of the inductor is based on the principle of electromagnetic induction, which states that a changing magnetic field will induce an electric current in a coil of wire. This induced current is then supplied to the circuit, allowing for a controlled flow of electrical energy.
