Overview

The Mersen GDG1/32 miniature time-delay fuse (SKU: GDG1/32) is a precision-engineered protective component designed for low-current applications requiring delayed fault response. Rated at 250VAC and 0.031A, this 5x20mm glass ferrule fuse combines high reliability with a compact form factor, making it ideal for sensitive electronic circuits where transient surges must be accommodated without nuisance tripping. The time-delay feature allows it to tolerate brief overcurrent conditions—such as startup inrush currents or transient voltage spikes—while providing robust protection against sustained faults. The glass ferrule construction ensures excellent thermal stability and mechanical strength, while the 5x20mm cylindrical design allows for easy integration into compact PCB assemblies, distribution panels, and instrumentation systems. Its 250VAC rating makes it suitable for use in both industrial control systems and consumer electronics operating on single-phase AC mains.
  • Rated 250VAC, 0.031A for low-current applications
  • Time-delay design tolerates transient surges and inrush currents
  • 5x20mm glass ferrule for thermal stability and mechanical strength
  • UL Listed and CSA Certified for 1/16A through 10A at 250VAC
