Common Mode Chokes

Common Mode Chokes (CMCs) are components designed to reduce noise between the source power supply and the load, by blocking the RF currents that can result from common-mode noise. CMCs are usually used in applications such as automotive, medical, and military/aerospace.The ELF-20N018A is an effective common-mode choke designed for a wide range of applications. It has a low-profile, cylindrical package, with an inductance on the order of 10nH. The ELF-20N018A is designed to reduce common-mode currents to very low levels, without affecting the differential-mode signals.The ELF-20N018A is composed of two ferrite cores that are arranged in a closed loop. In the loop, there are three windings: two inner windings and one outer winding. The inner windings are connected in series, and are wound on a single ferrite core. The outer winding is wound on the second ferrite core. The two cores are connected together to form a closed loop.The ELF-20N018A works by passing the unwanted common-mode noise current through the outer winding, while allowing the differential-mode signal to pass through the inner windings. The common-mode current is then shorted out by the outer winding, resulting in lower levels of noise. The differential-mode signal passes through the inner windings without any interference.The ELF-20N018A can be used in a variety of applications due to its low-profile, cylindrical design. It is an effective noise reduction solution for automotive, medical, and military/aerospace applications. It can be used to reduce EMI in electronic systems, such as cellphones, tablets, and medical/lab equipment. The ELF-20N018A is also an effective solution for wireless communication applications, such as Wi-Fi routers, satellite systems, and bluetooth devices.The ELF-20N018A is a highly effective component for reducing EMI in a variety of applications. Its low-profile, cylindrical design makes it easy to install in tight spaces. It is designed to reduce common-mode noise while allowing the differential-mode signal to pass through with minimal interference. The ELF-20N018A is an ideal choice for applications such as automotive, medical, and military/aerospace.
