Common mode chokes, otherwise known as common mode line filters or line-to-ground chokes, are devices used to limit the flow of common-mode currents on data lines and power lines. They typically consist of a ferromagnetic core wrapped with a coil wound in a common-mode configuration, allowing them to effectively block the common-mode frequency components that are present in the signal lines.

The ELF-18D417 is an example of a common mode choke, and it has a wide variety of applications. This device offers a very robust and cost-effective solution for most signal line filtering needs, including differential mode and common mode filtering. It is ideal for use in a variety of applications, such as telecommunications, robust military-grade smart sensors, automotive, and consumer electronics.

The working principle of the ELF-18D417 is based on the inductive properties of its ferromagnetic core. When high frequency signals are applied to the device, the core acts as an inductor, which absorbs and store excess energy. The core then releases this stored energy in the form of the desired frequency components, allowing the ELF-18D417 to act as a filter, blocking out the common-mode noise present in the signal line.

The ELF-18D417 offers high level of performance in terms of power handling and insertion loss. It has a low DCR (Direct Current Resistance) of 14.5Ω, allowing it to provide superior power handling capabilities. In terms of insertion loss, the device offers very low insertion loss up to 100KHz, and an even lower insertion loss up to 3KHz. The device also features very low leakage flux, ensuring that there is minimal EMI radiation.

The ELF-18D417 is designed to operate in a wide temperature range of -55 to +125℃. It is designed with a robust, lightweight housing, and its gold-plated contacts ensure reliable connection with a variety of cables and connectors. The device also features a variety of mounting options, including thru-hole, surface mount, and voice coil.

In conclusion, the ELF-18D417 is an excellent choice for filtering applications in a variety of sectors. Its high-performance characteristics, cost-effectiveness, and robust design make it an ideal choice for applications where common-mode noise is a problem. It is versatile and reliable, and its wide temperature range and mounting options make it even more convenient for use in a variety of applications.
