It is rated at 15A with 250V AC and 100V DC voltage ratings, providing high interrupting capability of 100A at 250V AC. The fuse offers superior thermal cycling endurance of 500 cycles with low temperature rise and excellent temperature stability. It is designed for datacom and telecom equipment including high-end servers, base stations, power supplies, and blade computing applications.","working_principle":"The 0463015.ER operates as a fast-acting sacrificial overcurrent protection device. Under normal operating conditions (current \u2264 15A), the fuse element conducts current with minimal voltage drop due to its low 4.7 m\u03a9 cold resistance. When an overcurrent condition occurs, the fuse element heats rapidly due to I\u00b2R power dissipation. The fast-acting characteristic means the element melts and opens the circuit quickly when the current exceeds approximately 200% of the rated current (opens within 60 seconds at 200% rated current). The ceramic body provides arc extinction capability to safely interrupt fault currents up to 100A AC.","pin_description":"<table>\n<tr><th>Terminal<\/th><th>Type<\/th><th>Function<\/th><\/tr>\n<tr><td>Terminal 1<\/td><td>Passive<\/td><td>Fuse input - connect to power source<\/td><\/tr>\n<tr><td>Terminal 2<\/td><td>Passive<\/td><td>Fuse output - connect to protected circuit<\/td><\/tr>\n<\/table>","application_scenarios":"<ul>\n<li>High-end server and blade computing overcurrent protection<\/li>\n<li>Base station power supply input protection<\/li>\n<li>Voltage regulator module (VRM) output protection<\/li>\n<li>ATCA blade and cloud computing chassis protection<\/li>\n<li>Battery management system short-circuit protection<\/li>\n<\/ul>","alternative_models":"<table>\n<tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr>\n<tr><td>Littelfuse<\/td><td>0463010.ER<\/td><td>4012<\/td><td>10A version, same series<\/td><\/tr>\n<tr><td>Littelfuse<\/td><td>0463020.ER<\/td><td>4012<\/td><td>20A version, same series<\/td><\/tr>\n<tr><td>Bel Fuse<\/td><td>5ST 15A<\/td><td>SMD<\/td><td>15A fast-acting SMD fuse<\/td><\/tr>\n<tr><td>Schurter<\/td><td>USF 15A<\/td><td>SMD<\/td><td>15A fast-acting SMD fuse<\/td><\/tr>\n<\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/posts\/10900","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/comments?post=10900"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/posts\/10900\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/media?parent=10900"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/categories?post=10900"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/tags?post=10900"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=10900"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
