Fast-Acting Chip Fuses
Table FF5 Electrical Specifications for Fast-Acting Chip Fuses
Insulation resistance after opening
20,000Ω minimum @ rated voltage. Fuse clearing under low voltage conditions may result in lower -
post-clearing insulation values. Under normal fault conditions values. Under normal fault conditions
Raychem fuses provide sufficient insulation resistance for circuit protection.
Withstands 100% rated current at +25°C ambient for 4 hours when evaluated per MIL-PRF-23419.

Recommended conditions for hand soldering:
1. Using hot air rework station that can reflow the solder on both terminations at the same time is strongly recommended,
do not directly contact the chip termination with the tip of soldering iron.
2. Preheating: 150°C, 60s (min).
Appropriate temperature (max) of soldering iron tip/soldering time (max): 280°C /10s or 350°C / 3s.
Maximum temperature of soldering iron tip/soldering time: 350°C /9s or 400°C / 8s.
