For high-volume automated production, this surface mount model is the preferred choice as it is compatible with standard SMT placement machines and reflow soldering processes. For high-temperature operating environments above 85\u2103, derate the current appropriately to ensure long-term reliability. Always match the fuse rating with the actual working current of the circuit, reserving a 1.25-1.5 times safety margin to avoid premature failure or insufficient protection.<\/p>\n<h2>Application Scenarios<\/h2>\n<ul>\n<li>Consumer electronics and household appliance control boards<\/li>\n<li>Switching power supplies, adapters and charger circuits<\/li>\n<li>Industrial control equipment and instrumentation<\/li>\n<li>Automotive electronic auxiliary systems<\/li>\n<li>Communication equipment and network terminals<\/li>\n<li>LED lighting drivers and smart home modules<\/li>\n<li>High-density PCB designs with limited board space<\/li>\n<\/ul>\n<h2>Installation &amp; Usage Notes<\/h2>\n<p>1. Select a matching 5x20mm cartridge fuse with appropriate current and voltage rating before use.<\/p>\n<p>2. Follow standard lead-free reflow soldering profiles to avoid housing deformation or contact oxidation caused by excessive temperature.<\/p>\n<p>3. Do not use the fuse holder beyond its rated voltage and current range to prevent insulation breakdown and safety hazards.<\/p>\n<p>4. Disconnect power before replacing the fuse to avoid electric shock and short-circuit damage.<\/p>\n<p>5. Store in a dry, dust-free and corrosion-free environment to prevent contact oxidation and performance degradation.<\/p>\n<p>6. For products used in harsh environments, additional conformal coating can be applied to improve reliability.<\/p>\n<p><a href=\"https:\/\/essfuse.com\/wp-content\/uploads\/2025\/12\/15S-1-1.pdf\">15S-1 (1)<\/a><\/p>\n<p>&nbsp;<\/p>","protected":false},"excerpt":{"rendered":"<p>5x20mm SMT fuse holder with UL94 V0 PBT housing and tin-plated copper alloy contacts, 10A 250VAC UL certified, lead-free reflow solderable for high density PCB overcurrent protection, RoHS compliant.<\/p>","protected":false},"featured_media":13092,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[148],"product_tag":[],"class_list":["post-13089","product","type-product","status-publish","has-post-thumbnail","product_cat-pcb-fuse-holder-clip","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/essfuse.com\/en_au\/wp-json\/wp\/v2\/product\/13089","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/essfuse.com\/en_au\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/essfuse.com\/en_au\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/essfuse.com\/en_au\/wp-json\/wp\/v2\/comments?post=13089"}],"version-history":[{"count":2,"href":"https:\/\/essfuse.com\/en_au\/wp-json\/wp\/v2\/product\/13089\/revisions"}],"predecessor-version":[{"id":13093,"href":"https:\/\/essfuse.com\/en_au\/wp-json\/wp\/v2\/product\/13089\/revisions\/13093"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/essfuse.com\/en_au\/wp-json\/wp\/v2\/media\/13092"}],"wp:attachment":[{"href":"https:\/\/essfuse.com\/en_au\/wp-json\/wp\/v2\/media?parent=13089"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/essfuse.com\/en_au\/wp-json\/wp\/v2\/product_brand?post=13089"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/essfuse.com\/en_au\/wp-json\/wp\/v2\/product_cat?post=13089"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/essfuse.com\/en_au\/wp-json\/wp\/v2\/product_tag?post=13089"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
