Introduction to Fixed Inductors

Fixed inductors are electrical components used to store energy in a magnetic field. They are used in a variety of applications including power supplies, motors, transformers, and other devices that need to convert electricity from alternating current (AC) to direct current (DC). Fixed inductors vary in size, construction, and purpose, depending on their application.

CTX20-2-52M-R Application Field and Working Principle

The CTX20-2-52M-R from TOKO is an Axial Toroidal Common Mode Choke specifically designed to reduce electromagnetic interference (EMI) and line-to-line conducted noise in various types of switching power supplies. This particular product features a metal-shield housing to provide strong immunity to external fields, along with a 20 mΩ impedance and a minimum DCR rating of 52mΩ.The working principle of the CTX20-2-52M-R is based on the electromagnetic induction principle. This means that when an alternating current (AC) flows through the primary winding of the inductor core, a magnetic field is generated around the winding. This magnetic field induces an electromotive force (EMF) in the secondary winding, which then causes a current to flow in the secondary winding. This produces an inductive reactance that opposes the change in primary current, thus limiting the current delivered to the load.Due to its high EMI / RFI suppression capabilities, the CTX20-2-52M-R is well-suited for use in a wide range of applications, including power supplies for computers and other electronic equipment, telecommunications equipment, medical equipment, automotive electronics, and home appliances. In addition, the device\'s low profile and rugged metal-shield housing makes it an ideal choice for applications where space is limited.

Conclusion

The CTX20-2-52M-R from TOKO is a high-performance Axial Toroidal Common Mode Choke designed to reduce EMI / RFI and line-to-line conducted noise in various types of switching power supplies. The device\'s low profile, rugged metal-shield housing, and 20mΩ impedance make it ideal for space-limited applications, and its high EMI / RFI suppression capabilities make it suitable for a range of applications including computers and other electronic equipment, telecommunications equipment, medical equipment, automotive electronics, and home appliances.
