Differential mode signals produce opposing magnetic fluxes that cancel out, allowing the signal to pass with minimal attenuation. Common mode noise produces additive magnetic fluxes, creating high impedance that blocks the noise current.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Description<\/th><\/tr><tr><td>1<\/td><td>Line 1 IN<\/td><td>Differential signal 1 input<\/td><\/tr><tr><td>2<\/td><td>Line 1 OUT<\/td><td>Differential signal 1 output<\/td><\/tr><tr><td>3<\/td><td>Line 2 IN<\/td><td>Differential signal 2 input<\/td><\/tr><tr><td>4<\/td><td>Line 2 OUT<\/td><td>Differential signal 2 output<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Smartphone SoC power rail decoupling<\/li><li>USB 2.0\/3.0 signal line EMI filtering<\/li><li>HDMI high-speed differential pair filtering<\/li><li>DC-DC converter input\/output noise suppression<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Brand<\/th><th>Type<\/th><th>Value<\/th><\/tr><tr><td>NFM41PC475B1A3D<\/td><td>Murata<\/td><td>3-terminal cap<\/td><td>4.7uF<\/td><\/tr><tr><td>ACM2012-900-2P<\/td><td>TDK<\/td><td>CMC<\/td><td>90ohm<\/td><\/tr><tr><td>DLP11SN900HL2L<\/td><td>Murata<\/td><td>CMC<\/td><td>90ohm<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts\/10169","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/comments?post=10169"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts\/10169\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/media?parent=10169"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/categories?post=10169"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/tags?post=10169"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=10169"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
