Using X7R dielectric material, it maintains capacitance within \u00b115% across the -55\u00b0C to +125\u00b0C temperature range. The 0805 (2.0\u00d71.25\u00d71.25mm) package with Ni-Sn three-layer termination provides reliable surface mount assembly. It is designed for general-purpose applications including power supply decoupling, filtering, and signal coupling.","working_principle":"The CL21B105KBFNNNF is constructed using alternating layers of ceramic dielectric (X7R formulation) and inner electrodes (Ni). The multiple layers are stacked and co-fired to form a monolithic block. The X7R dielectric is a Class II ferroelectric material (barium titanate based) that provides high volumetric capacitance. When voltage is applied, charge is stored at the electrode-dielectric interfaces. The many thin dielectric layers in parallel provide high capacitance in a compact volume. The three-layer termination (Cu inner \/ Ni barrier \/ Sn outer) prevents silver migration and ensures solder joint reliability.","pin_description":"Pin Description(Output pin definitions in table format only; return pure content without derivation or extra elaboration)","application_scenarios":"Application Scenarios (Output pin definitions in table format only; return pure content without derivation or extra elaboration)","alternative_models":"GRM21BR71H105KA01L (Murata); CC0805KRX7R9BB105 (Yageo); C2012X7R1H105K (TDK); CL21B105KBFNNNE (Samsung, different packaging)"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts\/10564","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=10564"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts\/10564\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/media?parent=10564"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/categories?post=10564"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/tags?post=10564"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=10564"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
