The hermetically sealed ceramic package prevents moisture ingress and ensures reliable operation in harsh environments. When overcurrent occurs, the fusible element melts and interrupts the circuit, with the arc extinguished within the ceramic body. The 300A breaking capacity ensures safe interruption of high fault currents.","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 fuse element<\/td><\/tr><tr><td>2<\/td><td>Terminal 2<\/td><td>Other end of fuse element<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Avionics and aerospace<\/li><li>Medical equipment<\/li><li>Defense electronics<\/li><li>Industrial control systems<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Spec<\/th><th>Package<\/th><\/tr><tr><td>0603FS1F<\/td><td>Bel Fuse<\/td><td>SMD fuse FF 125V<\/td><td>0603<\/td><\/tr><tr><td>0461001.NR<\/td><td>Littelfuse<\/td><td>SMD fuse FF 125V<\/td><td>1206<\/td><\/tr><tr><td>USL 0603 1A<\/td><td>Schurter<\/td><td>SMD fuse FF 63V<\/td><td>0603<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/9821","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=9821"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/9821\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=9821"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=9821"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=9821"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=9821"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
