WCM511 Series 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.
