Description
• End of life is June 30, 2006. Recommended
replacement is 0603FA-R Series
• Small, fast acting surface mount fuse
• Chip fuses utilize thick and thin metal film
technologies for superior fusing action and
enhanced reliability
• Excellent short-circuit performance and
environmental integrity
• End terminations are over-plated with nickel and
tin-lead
• Solder-free design provides excellent temperature
cycling characteristics
• Heat and shock tolerant

‡ Typical Voltage Drop (Measured at rated current after temperature stabilizes)
The fuses are randomly oriented in the carrier tape. 1608FF series fuses mounted with random orientation on circuit boards does not affect fuse performance.
Device designed to carry rated current for four hours minimum. An operating current of 80% or less of rated current is recommended, with further derating required at elevated
ambient temperatures.
