GF‑717 Vertical Mini Blade Fuse Clip | 30A THM Through‑Hole, Brass Tin‑Plated, ATN/297 Series
The GF‑717 is a vertical‑entry mini blade fuse clip. Specifically, it accepts MINI / ATN / 297‑series automotive blade fuses in a vertical through‑hole (THM) configuration. Furthermore, EssFuse builds this clip from brass with tin plating, and it handles 30A continuously. Therefore, designers choose it for densely packed automotive PCBs where horizontal fuse entry is blocked.
Product Overview
Core Design Purpose
The GF‑717 provides a through‑hole PCB socket for MINI blade fuses with vertical insertion. Besides, the vertical entry direction lets technicians insert and remove fuses from the top of the board. Consequently, it solves layout problems where adjacent components block horizontal fuse replacement.
Electrical Performance
Notably, the clip carries 30A. Brass contacts with tin plating keep contact resistance low. As a result, it maintains stable conductivity under continuous load. Moreover, the tin plating resists oxidation across the product’s service life.
Mechanical Design
The mounting holes are 2‑Ø1.7mm with 3.7mm center spacing. Meanwhile, the overall length stays at 11.2±0.2mm, so the footprint remains compact. In fact, the spring clip geometry holds the MINI fuse firmly while allowing hand insertion without special tools.

Application Solutions
1. Densely Packed Automotive PCB
For automotive ECU and body control boards with limited horizontal clearance, the GF‑717 vertical entry allows fuses to insert from the top. Specifically, this matters where adjacent components or enclosures block horizontal replacement. Furthermore, the through‑hole leads suit standard wave solder lines.
2. BMS & Industrial Control Board
In BMS and industrial control boards, the GF‑717 provides a compact vertical fuse socket. As a result, designers place the fuse near protected ICs without sacrificing board width. Therefore, trace length and parasitic inductance drop significantly.
3. Customization & OEM Support
EssFuse provides custom lead length, plating options, and tape‑and‑reel packaging. In addition, we supply matching MINI blade fuses. For instance, customers order the clip and fuse together to guarantee insertion force compatibility. Contact sales for the recommended PCB land pattern and free samples.
Typical Applications
Use Cases
- Automotive ECU / BCM compact PCB fuse protection
- Battery management system (BMS) vertical fuse clip
- Industrial control board and power supply
- EV / HEV auxiliary electronic control
- Home energy storage battery management board
- Densely packed PCB where horizontal entry is blocked
Customer Questions & Answers
Real Customer Questions
1: What is the difference between vertical and horizontal fuse entry?
A: Vertical entry means the fuse inserts perpendicular to the PCB (top‑down), which saves horizontal space. Horizontal entry means the fuse lies flat parallel to the board. For instance, choose vertical (GF‑717) when board width is tight; choose horizontal (GF‑717C / GF‑718B) when height clearance is limited.
2: Which fuses does it accept?
A: MINI / ATN / 297 series automotive blade fuses, size .110 (2.80 x 0.80mm). Notably, this is the small “mini” blade form factor. It does NOT accept ATO/ATC medium blade fuses.
3: Is it through‑hole or SMD?
A: Through‑hole (THM). The two Ø1.7mm mounting pins solder into plated through‑holes. Meanwhile, the mounting hole spacing is 3.7mm. We provide the recommended PCB land pattern on request.
4: What is the maximum current?
A: 30A. For enclosed PCBs with limited airflow, derate to 70–80% (21–24A). Consequently, this keeps temperature rise within safe limits. For continuous operation above 24A, consult our engineering team.
5: Do you supply matching MINI fuses?
A: Yes. We manufacture GFEFUSE GF‑C series MINI / ATN blade fuses that mate with this clip. As a result, ordering both from EssFuse guarantees insertion force and contact compatibility.
6: Is it RoHS compliant?
A: Yes. Brass with tin plating meets RoHS requirements. Furthermore, halogen‑free and special plating options are available on request.
7: Can you customize the lead length?
A: Yes. Custom lead length, lead forming, and packaging are available for high‑volume orders. Therefore, send your drawing or requirements to our sales team for a quote.
