Choose matching\u2011rating 5.2x20mm tubular fuses and reserve a 1.25\u20111.5\u00d7 safety margin to avoid over\u2011heating under continuous load. Select PBT or PA housing material according to PCB board ambient temperature requirements; green or black standard colors are available with custom\u2011color support for product appearance matching. Follow official PCB dimension drawing for pad layout, ensure proper through\u2011hole soldering quality to guarantee stable current\u2011carrying performance.<\/p>\n<h2>Typical Application Scenarios<\/h2>\n<ul>\n<li>Household appliance control PCB and consumer\u2011electronics circuits<\/li>\n<li>Power adapters, small switching power supplies and power\u2011supply boards<\/li>\n<li>Test instruments, multimeters and laboratory small\u2011power circuit boards<\/li>\n<li>Communication equipment and network\u2011device auxiliary protection circuits<\/li>\n<li>LED drivers and low\u2011power lighting\u2011control PCBA<\/li>\n<li>Industrial small\u2011automation modules and low\u2011voltage control boards<\/li>\n<\/ul>\n<h2>Installation &amp; Maintenance Instructions<\/h2>\n<p>1. Select correct\u2011rating 5.2 \u00d7 20\u202fmm glass \/ ceramic tubular cartridge fuse for your circuit\u2011protection requirements.<\/p>\n<p>2. Design PCB through\u2011hole pads strictly per official dimension drawing to ensure soldering compatibility.<\/p>\n<p>3. Complete wave\u2011soldering or hand\u2011soldering with appropriate temperature and dwell time; avoid over\u2011heat damage to plastic housing.<\/p>\n<p>4. Insert tubular fuse fully into holder cavity for reliable electrical contact.<\/p>\n<p>5. Do not operate beyond published rated voltage\u2011current limits to prevent insulation breakdown and safety hazards.<\/p>\n<p>6. Cut off power supply and discharge circuit before fuse replacement to prevent electric\u2011shock risk.<\/p>\n<p>7. Periodically check for loose fuse, contact oxidation or heating; replace components promptly when anomalies appear.<\/p>\n<p><a href=\"\/es\/PTF\u201177\u20115\u20112x20\u2011PCB\u2011Fuse\u2011Holder.pdf\/\">Download 5.2x20mm PCB Mount Fuse Holder Datasheet (PDF)<\/a><\/p>\n<h2>Frequently Asked Questions<\/h2>\n<p><strong>Q1: What fuse size fits this PCB mount fuse holder?<\/strong><\/p>\n<p>A1: It accepts standard 5.2 \u00d7 20\u202fmm glass and ceramic tubular cartridge fuses, widely\u2011used for consumer\u2011electronics PCB\u2011level over\u2011current\u2011protection.<\/p>\n<p><strong>Q2: What are the electrical ratings?<\/strong><\/p>\n<p>A2: Rated current range 0.1\u20116.3A; rated voltage 125V \/250V for both AC and DC, for small\u2011to\u2011medium\u2011current low\u2011voltage PCB circuits.<\/p>\n<p><strong>Q3: What housing material options are available?<\/strong><\/p>\n<p>A3: PBT or PA housing with UL94\u202fV0 flame\u2011retardant grade, green and black as standard colors, custom colors acceptable upon request.<\/p>\n<p><strong>Q4: What are terminal specifications?<\/strong><\/p>\n<p>A4: Terminals are made of 0.4\u202fmm \/0.5\u202fmm\u2011thick H65 brass; contact resistance \uff1c5\u202fm\u03a9 for stable long\u2011term conduction.<\/p>\n<p><strong>Q5: What are insulation and withstand\u2011voltage parameters?<\/strong><\/p>\n<p>A5: Contact resistance \uff1c5\u202fm\u03a9, insulation resistance\uff1e100\u202fM\u03a9, power\u2011frequency withstand voltage 3000V AC for reliable PCB\u2011side insulation safety.<\/p>\n<p><strong>Q6: What mounting style does it adopt?<\/strong><\/p>\n<p>A6: Through\u2011hole PCB soldering mount, compatible with wave\u2011soldering and manual soldering for printed circuit boards.<\/p>\n<p><strong>Q7: What are main application\u2011fields?<\/strong><\/p>\n<p>A7: Applied for household appliances, power adapters, test instruments, LED drivers, communication equipment and various low\u2011voltage PCB\u2011based over\u2011current\u2011protection circuits.<\/p>","protected":false},"excerpt":{"rendered":"<p>Industrial\u2011grade through\u2011hole PCB mount fuse holder for 5.2\u00d720mm tubular cartridge fuses, PBT\/PA UL94 V0 flame\u2011retardant housing with 0.4\/0.5mm H65 brass terminals, rated 0.1\u20116.3A 125V\/250V AC\/DC, &lt;5m\u03a9 contact resistance, 3000V AC withstand voltage, customizable green\/black colors for appliance, instrument and electronic PCB over\u2011current protection.<\/p>","protected":false},"featured_media":13860,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[148],"product_tag":[],"class_list":["post-4188","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\/es\/wp-json\/wp\/v2\/product\/4188","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/essfuse.com\/es\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/essfuse.com\/es\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/essfuse.com\/es\/wp-json\/wp\/v2\/comments?post=4188"}],"version-history":[{"count":3,"href":"https:\/\/essfuse.com\/es\/wp-json\/wp\/v2\/product\/4188\/revisions"}],"predecessor-version":[{"id":15465,"href":"https:\/\/essfuse.com\/es\/wp-json\/wp\/v2\/product\/4188\/revisions\/15465"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/essfuse.com\/es\/wp-json\/wp\/v2\/media\/13860"}],"wp:attachment":[{"href":"https:\/\/essfuse.com\/es\/wp-json\/wp\/v2\/media?parent=4188"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/essfuse.com\/es\/wp-json\/wp\/v2\/product_brand?post=4188"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/essfuse.com\/es\/wp-json\/wp\/v2\/product_cat?post=4188"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/essfuse.com\/es\/wp-json\/wp\/v2\/product_tag?post=4188"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
