The NANO2 Slo-Blo fuse has enhanced inrush withstand characteristics over the NANO2 Fast-Acting fuse. The unique time delay feature of this fuse design helps solve the problem of nuisance "opening" by accommodating inrush currents that normally cause a fast-acting fuse to open.


Features:

  • Time-Lag (Slo-Blo)
  • Small size 
  • Wide range of current rating available (375mA to 12A)
  • Wide operating temperature range
  • Low temperature de-rating
  • RoHS compliant
  • Halogen Free
