Common Mode Chokes (CMF-0056) are a popular type of filter used to limit and reduce electromagnetic or radio frequency interference in electrical circuits. They are designed to isolate certain signals from outside noise, and protect the connected equipment from damage or malfunction due to EMI/RFI.The CMF-0056 is a medium-power toroidal choke that utilizes a multilayer magnetic core and wire-wound construction to efficiently reduce a wide range of common mode impedance levels. The CMF-0056 is designed for use in a variety of applications, including power supplies, medical equipment, industrial and consumer electronics, audio/video equipment, computers, and appliances.The core material used in the CMF-0056 is a nanocrystalline material which has been carefully selected to provide maximum inductance while maintaining low losses. This material is capable of handling high-frequency current transients and DC biasing. Additionally, the CMF-0056 features an extruded plastic housing, designed to provide thermal stability and mechanical integrity. The toroidal shape of the CMF-0056 provides excellent magnetic characteristics and helps to decrease external leakage fields. This helps to reduce the possibility of interference with other equipment. The CMF-0056 is designed to operate in high-frequency applications up to 10 MHz and is capable of handling both AC and DC currents.The typical common mode impedance of the CMF-0056 is between 10k and 20k Ohms. However, the impedance level can be customized by varying the number of turns, wire size, core material, and casing size. The combination of materials and construction used in the CMF-0056 helps to maximize the inductance of the choke and thus improve its noise filtering capability.The CMF-0056 works by suppressing both the common mode and differential mode current. The common mode current is the same current that flows in both wires of the transmission line, while the differential mode current flows only in one wire. The CMF-0056 reduces the amount of noise entering the system by blocking the common mode current which is then dissipated as heat by the choke. The CMF-0056 is designed to reject interference in applications where RFI is an issue. It has a wide frequency range, is RoSh compliant, and provides both safety and performance benefits in sensitive applications. As an added convenience, the CMF-0056 is RoHS compliant and offers universal mounting options. It is available in a variety of sizes and has a wide dynamic range to meet various EMI/RFI filter requirements.The CMF-0056 is an economical and practical option for reducing EMI/RFI interference and ensuring the safety of sensitive systems. Its small size and universal mounting options make it ideal for a wide range of applications, from medical to industrial. It provides superior EMI/RFI shielding and is capable of handling both AC and DC current at high frequencies. Its excellent inductance makes it ideal for noise reduction applications requiring low-impedance filtration.
