When overcurrent exceeds 2.2A, the polymeric material self-heats causing a phase transition that dramatically increases resistance to 210m ohm max, limiting current. When the fault clears and the device cools, it automatically resets.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Terminal 1<\/td><td>Circuit connection<\/td><\/tr><tr><td>2<\/td><td>Terminal 2<\/td><td>Circuit connection<\/td><\/tr><\/table>","application_scenarios":"<ul><li>USB port overcurrent protection<\/li><li>Hard disk drive current limiting<\/li><li>PC motherboard peripheral protection<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Spec1<\/th><th>Spec2<\/th><\/tr><tr><td>PFMF.110.16.2<\/td><td>SCHURTER<\/td><td>16V\/1.1A<\/td><td>1812<\/td><\/tr><tr><td>MF-MSMF110-2<\/td><td>Bourns<\/td><td>6V\/1.1A<\/td><td>1812<\/td><\/tr><tr><td>0ZCJ0011FF2E<\/td><td>Bel Fuse<\/td><td>6V\/1.1A<\/td><td>1812<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9715","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=9715"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9715\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=9715"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=9715"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=9715"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=9715"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
