WCM509 Series Common Mode Chokes

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!
