Under normal operating conditions, the alloy conducts current. When the ambient temperature exceeds the rated cutoff temperature, the alloy melts and a spring mechanism separates the contacts, permanently opening the circuit. Unlike PTC devices, thermal fuses are one-time devices and must be replaced after activation.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Lead 1<\/td><td>One terminal of thermal element<\/td><\/tr><tr><td>2<\/td><td>Lead 2<\/td><td>Other terminal of thermal element<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Power supply overtemperature protection<\/li><li>Motor thermal protection<\/li><li>Transformer thermal cutoff<\/li><li>Appliance safety protection<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Spec<\/th><th>Package<\/th><\/tr><tr><td>A70-300-4470<\/td><td>Schott<\/td><td>Thermal fuse<\/td><td>Axial<\/td><\/tr><tr><td>NEC SDF DF192S<\/td><td>NEC<\/td><td>Thermal fuse<\/td><td>Axial<\/td><\/tr><tr><td>G4A00217<\/td><td>Cantherm<\/td><td>Thermal fuse<\/td><td>Axial<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/9805","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=9805"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/9805\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=9805"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=9805"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=9805"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=9805"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
