Overview

The Mersen GDG-V16/100 miniature time-delay fuse is a high-performance, glass-body protective device engineered for applications requiring reliable overcurrent interruption in low-voltage AC circuits. Designed with a 250VAC rating and 0.16A current rating, this 5x20mm fuse is optimized for sensitive electronics, control panels, and instrumentation where transient surges are common. Its time-delay characteristic ensures temporary overloads—such as startup currents in motors or capacitors—do not trigger unnecessary interruptions, while still providing robust protection against sustained faults. The soldered axial leads facilitate secure, permanent connections in compact enclosures, making it ideal for space-constrained designs in industrial, commercial, and OEM applications. This fuse is part of Mersen’s GDG-V series, a trusted line of miniature fuses known for exceptional consistency and durability across diverse operating environments. Whether deployed in power supplies, automation systems, or test equipment, the GDG-V16/100 delivers predictable performance with minimal drift over time. Its glass body allows for visual inspection of the fuse element, enabling quick diagnostics during maintenance or troubleshooting. Additionally, the 5x20mm form factor is a global standard, ensuring compatibility with a vast ecosystem of fuse holders, clips, and panels—reducing inventory complexity and simplifying system design. Professionals in electrical engineering, panel building, and equipment manufacturing rely on Mersen for its heritage of innovation and safety leadership in fuse technology. The GDG-V16/100 is manufactured to meet stringent international standards, including UL 248 and IEC 60127, ensuring compliance with global safety and performance requirements. Its time-delay design is particularly advantageous in applications such as: - **Power supplies and converters** – Handles inrush currents from capacitors and transformers without nuisance tripping. - **Industrial control systems** – Protects PLCs, relays, and sensors from overloads in harsh environments. - **Test and measurement equipment** – Safeguards sensitive circuits during calibration or transient events. - **Lighting ballasts and LED drivers** – Provides stable protection for electronic lighting systems. - **Telecom and datacom infrastructure** – Ensures uptime in critical communication networks. Installation is straightforward: the axial leads are designed for soldering directly to PCB traces or terminal blocks, offering a low-resistance connection that minimizes heat buildup. For optimal performance, ensure the fuse is mounted in a location with adequate ventilation and away from heat sources. When selecting a fuse, consider the maximum ambient temperature, expected surge duration, and circuit inrush characteristics to match the time-delay curve to your application’s needs. Mersen provides detailed time-current curves and technical documentation to support precise sizing. Choosing Mersen means partnering with a company that has been at the forefront of electrical protection for over a century. The GDG-V16/100 exemplifies Mersen’s commitment to quality, with rigorous testing for breaking capacity, temperature cycling, and vibration resistance. Whether you’re designing a new system or replacing an existing fuse, the GDG-V16/100 offers a dependable, cost-effective solution that enhances system reliability and longevity. Trust Mersen to deliver the protection your circuits deserve.
