Common Mode Chokes

WCM’s new 511 series common mode choke was released for noise sensitive applications requiring a very high level of noise rejection. With peak impedance values for 10 kOhms 90 kOhms, these chokes will ensure that your power supply has exceptionally low noise interference. The 511 series was designed in a surface mount package to ensure ease of installation. Using nanocrystalline magnetic cores, the WCM511 series common mode chokes have stable properties over a wide temperature range.

WCM is pleased to announce the introduction of a standard product line of surface mount common mode chokes that utilize the high attenuation benefits of nano-crystalline material. These chokes can obtain minimum inductances up to 116mH while being able to handle up to 8.7A of current with reasonable operating temperature increases. There are three different form factors to choose, resulting in a tailored fit to your common mode noise attenuation application. All form factors are pick-and-place compatible to meet the high volume production demands. Please contact a knowledgeable engineer at West Coast Magnetics to discuss your application today!

They provide high attenuation levels at operating currents up to 52A. Utilizing nano-crystalline technology allows for more attenuation inside a smaller footprint; ferrite cores can not achieve the levels of attenuation offered by WCM’s 510 series.
