GF‑717N | Mini Low‑Profile Blade Fuse Holder
Our GF‑717N Mini Low‑Profile Blade Fuse Holder is a THT PCB‑mount fuse clip built exclusively for low‑profile mini automotive blade fuses. Specifically, it supports up to 30A current under 250VAC working condition. In addition, it adopts glass‑fiber reinforced PBT base material with UL94V‑0 flame retardant grade for outstanding high‑temperature stability. Furthermore, 0.30 mm thick brass terminals receive tin‑plated finishing, which keeps maximum contact resistance below 50 mΩ. It delivers minimum 1 kg insertion‑withdrawal force to lock fuses firmly. Moreover, engineers widely select this compact holder for automotive electronic boards, new‑energy controllers and industrial PCB over‑current protection.

الأسئلة الشائعة
1: Which fuse fits GF‑717N fuse holder?
1: This PCB‑mount clip matches standard mini low‑profile automotive blade fuses only; it cannot work for regular full‑size mini blade fuses.
2: What is the rated electrical capacity for GF‑717N?
2: It reaches 30A rated current at 250VAC. However, apply proper current derating under high‑temperature or continuous heavy‑load working conditions.
3: What material makes up the base housing?
3: The insulator base uses glass‑fiber reinforced PBT material, and it meets UL94V‑0 flame retardant safety standard.
4: How strong is the fuse holding force?
4: The insertion‑withdrawal force stays minimum 1 kg. Therefore, it holds fuses tightly even under mechanical vibration for automotive equipment.
5: What value is the maximum contact resistance?
5: Maximum contact resistance is 50 mΩ. Low contact resistance helps to reduce heat generation at contact points.
6: Can GF‑717N work in extreme cold or high‑heat environment?
6: Yes, its operating temperature spans from ‑40 °C to +115 °C. It suits outdoor automotive and industrial devices with wide temperature fluctuation.
7: What mounting process does GF‑717N support?
7: It is through‑hole THT type, fit for wave soldering. It is not designed for SMD reflow soldering process.
