Common Mode Chokes (CMCs) are electronic components used in applications such as power supplies, circuit boards and motor control systems, to reduce the level of interference and noise. The FE2X39-4-3NL CMC is a compact three-terminal integrated passive component used for suppressing common and noise mode currents at high frequencies in automotive and consumer electronics applications. This CMC features a wide working frequency range of 0.1 MHz to 6 MHz and is housed in a small, low-profile 0603 package.

The CMC’s working principle is based on Faraday’s Law of Electromagnetic Induction, which states that a voltage is induced in a conductor when a magnetic field is varied in time. This voltage is in the opposite direction to the change in the magnetic field. The FE2X39-4-3NL CMC uses this principle to reduce the common and noise mode currents on its terminals. It comprises of an inductive core, which captures the common mix and noise mode currents and generates a voltage which works against their flow.

The FE2X39-4-3NL CMC can be used in a wide range of applications including car audio systems, computer monitors, optical digital-to-analog converters, power supplies, switching power supplies and power amplifiers. It is also suitable for high frequency filters and attenuators in these applications. The CMC is designed to have an impedance level which rises linearly with frequency, thus providing effective suppression of both common mix and noise mode currents in a wide range of high frequencies.

The FE2X39-4-3NL CMC is a robust component that can operate in an extended temperature range from -40°C to 125°C, and has a self-resonant frequency of 12MHz. It also has an inductance range of 0.83uH to 10uH for lower frequency applications and 1.60uH to 10uH for applications that require a higher frequency range.

In conclusion, the FE2X39-4-3NL CMC is an efficient electronic component that can be used to reduce common and noise mode currents in a variety of high frequency applications. It features a wide working frequency range, low profile package, extended temperature range and robust construction.
