PCB mount fuse holder<\/strong> for 5x20mm cartridge fuses is a through\u2011hole soldered circuit\u2011protection component for consumer and industrial low\u2011voltage PCBA. This fuse base adopts high\u2011performance PBT UL94\u202fV\u20110 insulating housing together with reliable H65 brass contact points, providing stable current\u2011carrying performance and good heat\u2011resistance. Designed for direct through\u2011hole PCB soldering assembly, it supports automated wave\u2011soldering production workflows. Widely deployed in power adapters, household appliances, test instruments and small\u2011power industrial control PCB boards.<\/p>\n Different from panel\u2011mount fuse holders, this through\u2011hole variant is fully board\u2011mounted to save enclosure space. Its wide\u2011temperature\u2011range performance makes it suitable for power\u2011adapter PCBA and equipment where PCB local temperature rise occurs.<\/p>\n Note: Original drawing document does not provide contact resistance, insulation resistance and withstand\u2011voltage parameters.<\/em><\/p>\n When selecting this through\u2011hole PCB mount fuse holder for 5×20\u202fmm fuses, confirm fuse dimension, system AC\u2011DC voltage and continuous operating current first. Select matching\u2011rating 5×20 glass\/ceramic cartridge fuses and keep a 1.25\u20111.5\u00d7 safety margin against continuous\u2011load overheating. For PCBA with high local operating temperature, this\u201125\u2103~+125\u2103 wide\u2011temperature\u2011range variant is recommended. Strictly follow official PCB layout drawing for pad design to guarantee soldering reliability and current\u2011carrying performance.<\/p>\n 1. Select correct\u2011rating 5×20\u202fmm glass \/ ceramic cartridge fuse according to circuit\u2011protection requirements.<\/p>\n 2. Design PCB through\u2011hole pads strictly follow product dimension drawing to ensure soldering compatibility.<\/p>\n 3. Complete wave\u2011soldering or manual soldering with proper temperature and dwell\u2011time; avoid over\u2011heating which will damage PBT housing.<\/p>\n 4. Insert cartridge fuse fully into holder cavity to achieve reliable electrical contact.<\/p>\n 5. Do not operate beyond published rated voltage\u2011current limits to avoid insulation breakdown and safety risks.<\/p>\n 6. Cut\u2011off full power supply and discharge circuit before fuse replacement to prevent electric\u2011shock hazard.<\/p>\n 7. Periodically inspect for loose fuse, contact oxidation or heating signs; replace components promptly when anomalies are found.<\/p>\nCore Product Features<\/h2>\n
