Overview

Mersen SKU S087025 is a 5x20mm miniature fuse designed for semiconductor and sensitive electronic circuit protection. This 6.3 Ampere, 250 Volt AC fuse features a medium time-lag characteristic (SA) that balances surge tolerance with fault interruption. The SA time-lag allows temporary inrush currents during equipment startup or transient conditions without nuisance tripping, while still providing reliable overcurrent protection for sustained fault conditions. This fuse is optimized for protecting delicate semiconductor devices and control apparatus where precise current handling is critical. The SA clip mounting configuration enables secure installation in compatible fuse holders, ensuring stable electrical contact and easy replacement. Part of Mersen's 5x20mm semiconductor protection fuse series, this unit operates across 125-250V applications and is available in box quantities of 50 pieces. The compact 5x20mm form factor makes it suitable for space-constrained installations while maintaining high reliability standards. This fuse is specifically engineered for applications requiring medium time-lag protection against overcurrent conditions in electronic circuits.
  • 5x20mm miniature fuse for semiconductor protection
  • Medium time-lag (SA) characteristic for surge tolerance
  • Rated for 125V-250V AC applications
