PCB‑mount fuse holders and clips accessories for 5.2x20mm cartridge fuses are through‑hole soldered circuit‑protection accessories for low‑voltage electronic PCBA. This fuse‑clip assembly uses high‑grade black PBT / PA UL94 V0 flame‑retardant insulating housing paired with durable H65 brass spring terminals. It delivers low contact‑resistance, high insulation strength and stable electrical performance for both AC and DC circuits. Designed for through‑hole PCB wave‑soldering mass‑production with 22.5 mm pin pitch. Black housing is available as a variant besides green, custom colors are acceptable. Widely used as standard fuse accessories for power adapters, household appliances, test instruments and general‑purpose electronic control boards.
Core Product Features
- Compatible with standard 5.2 × 20 mm glass / ceramic tubular cartridge fuses for low‑voltage PCB‑level over‑current‑protection
- Electrical rating: 0.1‑6.3A, 125V / 250V AC/DC, covers small‑current consumer‑electronic circuit‑protection needs
- Housing material: PBT / PA, UL94 V‑0 flame‑retardant grade; black housing variant available (green as alternative)
- Terminal: 0.4 mm / 0.5 mm thickness H65 brass spring contacts, stable spring‑clamping performance
- Contact resistance below 5 mΩ; insulation resistance greater than 100 MΩ; power‑frequency withstand voltage 3000V AC
- Through‑hole PCB soldering mount, 22.5 mm pin‑pitch, fits conventional wave‑soldering manufacturing workflows
- Multiple housing‑color options: black / green, custom colors supported upon project request
- RoHS‑compliant construction, meets global consumer‑electronics safety and environmental‑protection standards.
These black PCB fuse holders and clips serve as complete fuse accessories for printed‑circuit‑board integration. Different from panel‑mount fuse bases, this clip‑style PCB‑mount accessory saves cabinet‑internal space and allows fuse replacement directly on PCBA. Dual‑material PBT/PA housing and color‑selectable options offer high flexibility for consumer‑electronic and instrument design projects.

Selection & Application Guidance
When selecting these PCB fuse holders & clips accessories for 5.2×20 mm fuses, confirm fuse dimension, system AC‑DC voltage and continuous operating‑current first. Select matching‑rating 5.2x20mm tubular fuses and reserve a 1.25‑1.5× safety margin to avoid over‑heating under continuous‑load. Choose black or green housing variant according to your PCBA visual‑layout requirements. Follow official 22.5 mm pin‑pitch PCB layout drawing for pad design to guarantee soldering reliability and stable contact performance. This is PCB‑mount accessory; proper enclosure protection shall be considered in final finished‑equipment design.
Typical Application Scenarios
- Power‑adapter and small switching‑power‑supply PCBA fuse accessories
- Household‑appliance control‑board and consumer‑electronics protection circuits
- Test instruments, multimeters and laboratory small‑power circuit‑boards
- Communication‑equipment auxiliary power‑input protection accessories
- LED power‑drivers and low‑voltage lighting‑control PCBA
- Small‑industrial‑automation module PCB over‑current‑protection accessories
Installation & Maintenance Instructions
1. Select correct‑rating 5.2 × 20 mm glass / ceramic tubular cartridge fuse according to circuit‑protection requirements.
2. Design PCB through‑hole pads strictly follow 22.5 mm pin‑pitch dimension drawing to ensure soldering compatibility.
3. Complete wave‑soldering or manual‑soldering with proper temperature and dwell‑time; avoid over‑heat damage to PBT / PA plastic housing.
4. Insert tubular fuse fully into clip cavity for reliable electrical contact.
5. Do not operate beyond published rated voltage‑current limits to prevent insulation breakdown and safety hazards.
6. Cut‑off full power supply and discharge circuit before fuse replacement to prevent electric‑shock hazard.
7. Periodically inspect for loose fuse, contact‑clip oxidation or heating signs; replace accessories promptly when anomalies are found.
