With WE-CCMF, Würth Elektronikoffers a compact multilayer common mode choke in a 0504 package which ischaracterized by high common mode attenuation in the WiFi frequencyrange (> 30 dB @ 2450 MHz). WE-CCMF is the solution to improve thesensitivity of Wireless LAN and Bluetooth enabled devices (notebooks,laptops, routers, IoT devices) that also include interfaces withhigh-speed push-pull signal transmission. These devices include USB3.1/3.2, SATA 3.0/3.2, HDMI 1.4/2.0 or Thunderbolt 2/3.
The high switching frequency of state-of-the-art data lines has made common mode interference a problem in radio reception. The ceramiccommon mode choke WE-CCMF achieves excellent attenuation in just this2.45 GHz range. The LTCC design of the WE-CCMF ensures low losses andhigh reliability. The reflow solderable SMT component has hightemperature stability and is suitable for operating temperatures from-40°C to +85°C. The push-pull cut-off frequency of the choke is 8 GHz.WECCMF is now available from stock without a minimum order quantity. Free samples can be requested.
