5.2x20mm PCB 장착형 퓨즈 홀더 및 클립 | 검정색 산업용 퓨즈 액세서리
Industrial‑grade black PCB‑mount fuse holders & clips accessories for 5.2×20mm glass & ceramic cartridge fuses, PBT/PA UL94 V0 flame‑retardant housing, 0.4/0.5mm H65 brass terminals, rated 0.1‑6.3A 125V/250V AC/DC, 3000V AC withstand voltage, >100MΩ insulation resistance, through‑hole 22.5mm pin‑pitch soldering mount, black housing variant for power adapters, household appliances and PCB‑level over‑current protection accessories.
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.
핵심 제품 특징
- 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.

선발 및 지원 안내
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.

설치 및 유지 관리 지침
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. 절연 파괴 및 안전 위험을 방지하기 위해 명시된 정격 전압-전류 제한을 초과하여 작동하지 마십시오.
6. 감전 위험을 방지하기 위해 퓨즈 교체 전에 전원 공급을 완전히 차단하고 방전 회로를 차단하십시오.
7. 퓨즈가 헐거워졌는지, 접점 클립에 산화가 발생했는지 또는 과열 흔적이 있는지 주기적으로 점검하십시오. 이상이 발견되면 부속품을 즉시 교체하십시오.
