PCB mount fuse holder<\/strong> for 5x20mm cartridge fuses is a through\u2011hole soldered circuit\u2011protection component for low\u2011voltage electronic PCBA. This fuse base uses high\u2011grade PA UL94 V0 flame\u2011retardant insulating housing, with low contact\u2011resistance metal contacts, PC1 shock\u2011safe construction, and complies with EN, UL, CSA safety standards. Designed for through\u2011hole PCB wave\u2011soldering assembly; standard housing color is green, custom colors available upon request. Widely deployed in power adapters, household appliances, test instruments and general\u2011purpose electronic control boards.<\/p>\n Different from panel\u2011mount fuse holders, this through\u2011hole PCB\u2011mount variant saves enclosure space, allowing fuse replacement directly on printed circuit boards. PC1 shock\u2011safe structure plus multi\u2011national safety certifications make it well\u2011suited for export\u2011oriented electronic device projects.<\/p>\n Note: Original datasheet does not provide insulation resistance and withstand\u2011voltage parameters.<\/em><\/p>\n When selecting this 5×20\u202fmm PCB\u2011mount fuse holder, confirm fuse dimension, system AC voltage and continuous operating current first. Choose matching\u2011rating 5x20mm tubular fuses and reserve a 1.25\u20111.5\u00d7 safety margin to avoid over\u2011heating under continuous load. For export\u2011targeted electronic products, verify compliance with EN \/ UL \/ CSA specifications. Follow official PCB layout drawing for pad design to guarantee soldering reliability and stable contact performance. Take IP00 rating into consideration for final equipment enclosure mechanical protection design.<\/p>\n 1. Select correct\u2011rating 5.2 \u00d7 20\u202fmm glass \/ ceramic tubular cartridge fuse for your circuit\u2011protection requirements.<\/p>\n 2. Design PCB through\u2011hole pads strictly per official dimension drawing to ensure soldering compatibility.<\/p>\n 3. Complete wave\u2011soldering or hand\u2011soldering with appropriate temperature and dwell\u2011time; avoid over\u2011heat damage to PA plastic housing.<\/p>\n 4. Insert tubular fuse fully into holder cavity for reliable electrical contact.<\/p>\n 5. Do not operate beyond published rated voltage\u2011current limits to prevent insulation breakdown and safety hazards.<\/p>\n 6. Cut off power supply and discharge circuit before fuse replacement to prevent electric\u2011shock risk.<\/p>\n 7. Periodically check for loose fuse, contact oxidation or heating; replace components promptly when anomalies appear.<\/p>\nCore Product Features<\/h2>\n
