GF‑717C Mini Blade Fuse Holder Clip | PCB Horizontal Mount, 30A 500VAC, Brass H65 Contacts
The GF‑717C is a PCB horizontal‑mount mini blade fuse holder clip manufactured by EssFuse. Specifically, it is designed for small‑car MINI blade plug‑in fuses (GFEFUSE GF‑C series mini fuses). With brass H65 contacts at 0.3mm thickness and tin‑plated terminals, this clip supports rated current up to 30A at 500VAC. Furthermore, it withstands reflow / wave soldering temperature of 260°C for 3 seconds, making it suitable for automated PCB assembly. Therefore, this mini fuse clip is widely used in automotive PCBs, battery management boards, and industrial power electronics.
Product Overview
Core Design Purpose
The GF‑717C mini fuse clip targets printed circuit board (PCB) horizontal mounting. Besides, it mates with GFEFUSE GF‑C series mini car insert fuses, providing a removable fuse connection directly on the PCB. Unlike panel‑mount fuse holders, this clip solders directly to the board, saving enclosure space.
Electrical Performance
Notably, the GF‑717C handles 30A at 500VAC. Contact resistance stays within 50mΩ maximum. As a result, it maintains stable conductivity even under continuous load. Moreover, dielectric strength reaches AC 1000V minimum, confirming robust isolation between contact paths.
Mechanical & Soldering Performance
The insertion and extraction force meets 1kg minimum, ensuring the mini fuse seats firmly. In addition, the clip survives soldering at 260°C for 3 seconds, compatible with standard SMT wave solder and reflow processes. Temperature rise remains below 130°C maximum.

Solutions We Provide
Application Solutions
1. Automotive PCB Fuse Protection
For automotive electronic control unit (ECU) and body control module (BCM) manufacturers, the GF‑717C offers a board‑level removable fuse connection. Specifically, the 260°C / 3s soldering rating matches standard wave solder lines, eliminating hand‑soldering bottlenecks. Furthermore, the 1kg insertion force allows service technicians to replace fuses without special tools.
2. Battery Management System (BMS) Board
In BMS and power distribution boards, the GF‑717C provides a compact mini‑fuse clip that protects MOSFETs and traces from overcurrent. As a result, designers can place removable fuses directly next to protected ICs, reducing trace length and inductance. Therefore, this improves both reliability and serviceability.
3. Customization & PCB Footprint Support
EssFuse provides the recommended PCB land pattern (footprint) drawing for the GF‑717C. In addition, we support custom contact thickness, lead length, and tape‑and‑reel packaging for high‑volume SMT assembly. Contact sales for the land pattern drawing and samples.

- Industrial power supply and converter PCB protection
- EV / HEV auxiliary electronic control board
- Home energy storage battery management board
- Smart meter and industrial control PCB fuse mounting
Customer Questions & Answers
Real Customer Questions
1: Is this a through‑hole or SMD part?
A: It is a through‑hole PCB horizontal mount clip. The leads are soldered into plated through‑holes on the PCB. It is not a surface‑mount (SMD) component. We provide the recommended land pattern drawing on request.
2: Which fuse does it accept?
A: It accepts mini (small car) blade plug‑in fuses, specifically the GFEFUSE GF‑C series mini fuses. This is the smaller “mini” form factor, not the ATO / ATC medium blade fuse (which uses the GF‑718 holder).
3: Can it survive reflow soldering?
A: Yes. The clip withstands 260°C for 3 seconds, which covers standard wave soldering and most reflow profile peak temperatures. For SMT reflow oven processing, confirm the exact thermal profile with our engineering team.
4: What is the continuous current rating?
A: 30A at 500VAC is the rated value. For enclosed PCB applications with limited airflow, we recommend derating to 70–80% (21–24A) to keep temperature rise below the 130°C maximum limit.
5: Why is the temperature rise 130°C while GF‑C41 is 50°C?
A: The GF‑717C is a PCB‑mount clip with thinner brass (0.3mm) and smaller contact area, so it runs hotter. The GF‑C41 is a panel‑mount holder with thicker brass (0.4mm) and better heat dissipation. Always verify the actual board temperature under load.
6: Do you supply the matching mini fuses?
A: Yes. We manufacture the GFEFUSE GF‑C series mini blade fuses that mate with this clip. Ordering the clip and fuse from one supplier ensures mechanical compatibility and consistent insertion force.
7: Is RoHS compliance available?
A: Yes. Standard tin plating is RoHS compliant. Halogen‑free or special plating options are available on request. We provide RoHS and REACH declarations upon formal order.
