Common Mode Chokes (CMFs) are widely used in the electrical and electronic industries to reduce the amount of electromagnetic interference (EMI) present in a system. The CMF23H-273141-B is one of the most commonly used CMF in various applications. This article outlines the application field and working principle of CMF23H-273141-B.

CMF23H-273141-B is mainly used in automotive systems such as engine control modules (ECMs), electronic fuel injection systems (EFI) and audio systems, as well as communication systems, home appliances, industrial control systems, and instrumentation systems. In these applications, CMF23H-273141-B helps to suppress common-mode noise generated by the in-circuit components, thus providing improved performance and reliability of the system.

CMF23H-273141-B is able to suppress common-mode noise due to its superior inductive coupling characteristics. It is constructed with two windings of a thin and flexible copper wire in a grounded, mu-metal shield core. The two windings are wound in parallel in opposite directions and have a common number of turns. This construction creates a magnetic field in the common-mode direction that opposes current flowing in the system, thus suppressing common-mode noise.

Apart from common-mode noise suppression, the other important features of CMF23H-273141-B are low DCR and high self-inductance. These features make CMF23H-273141-B suitable for use in applications that operate at high frequencies, such as in automotive systems. Furthermore, the mu-metal shielding ensures that the interference generated by the magnetic fields is localized within the core, and thus does not affect other components in the circuit.

In conclusion, CMF23H-273141-B is an effective common-mode choke with excellent inductive coupling characteristics. It is widely used in various applications, such as automotive, communication, and industrial systems, to reduce EMI and maintain system performance and reliability. It features low DCR, and high self-inductance, coupled with a mu-metal shielding, to ensure that the interference generated by the magnetic fields is localized to the core.
