Under normal current (below 1.5A), the conductive paths provide low resistance. When overcurrent occurs, Joule heating raises the polymer temperature above its crystalline transition point, causing expansion that breaks the conductive paths and dramatically increases resistance. When the fault is removed and the device cools, the polymer contracts and the conductive paths reform, resetting the device to its low-resistance state.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Terminal 1<\/td><td>One end of PTC element<\/td><\/tr><tr><td>2<\/td><td>Terminal 2<\/td><td>Other end of PTC element<\/td><\/tr><\/table>","application_scenarios":"<ul><li>USB port protection<\/li><li>Battery pack protection<\/li><li>Low-voltage DC power protection<\/li><li>Consumer electronics overcurrent protection<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Spec<\/th><th>Package<\/th><\/tr><tr><td>MF-MSMF150-2<\/td><td>Bourns<\/td><td>1.5A 6V 1206 PTC<\/td><td>1206<\/td><\/tr><tr><td>nSMD150-6V<\/td><td>Littelfuse<\/td><td>1.5A 6V 1206 PTC<\/td><td>1206<\/td><\/tr><tr><td>0ZCJ0150FF2E<\/td><td>Bel Fuse<\/td><td>1.5A 6V 1206 PTC<\/td><td>1206<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/9836","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=9836"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/9836\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=9836"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=9836"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=9836"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=9836"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
