Common mode chokes are essential passive components that suppress common mode noise while allowing differential signals to pass with minimal attenuation, making them critical for maintaining signal quality in communication and data transmission systems.","working_principle":"Common mode chokes operate by presenting high impedance to common mode (same-direction) noise currents while presenting low impedance to differential mode signals. The two windings are wound on a common magnetic core such that the magnetic flux from differential signals cancels out (allowing signal passage), while common mode noise fluxes add together (creating high impedance that blocks noise). This selective filtering mechanism preserves signal integrity while eliminating EMI.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Line A In<\/td><td>Input<\/td><td>Differential line A input<\/td><\/tr><tr><td>2<\/td><td>Line B In<\/td><td>Input<\/td><td>Differential line B input<\/td><\/tr><tr><td>3<\/td><td>Line A Out<\/td><td>Output<\/td><td>Differential line A output<\/td><\/tr><tr><td>4<\/td><td>Line B Out<\/td><td>Output<\/td><td>Differential line B output<\/td><\/tr><\/table>","application_scenarios":"<ul><li>USB 2.0\/3.0 interface EMI filtering<\/li><li>HDMI signal line noise suppression<\/li><li>LAN Ethernet common mode filtering<\/li><li>Differential signal pair noise reduction<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>Murata<\/td><td>DLM31SN121<\/td><td>3216<\/td><td>Common mode choke equivalent<\/td><\/tr><tr><td>Taiyo Yuden<\/td><td>BFHD31SN121TV<\/td><td>SMD<\/td><td>Similar specification<\/td><\/tr><tr><td>Wurth<\/td><td>744231200<\/td><td>SMD<\/td><td>Common mode choke<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9870","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=9870"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9870\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=9870"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=9870"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=9870"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=9870"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
