General Information:  
Packaging and Ordering Information:  
Tape and Reel: Standard 8mm tape, in compliance with  
EIA-RS481 (equivalent to IEC 286, Part 3).  
Bussmann SMT Chip Fuses utilize thick and thin metal  
film technologies for superior fusing action and enhanced  
reliability.  
The fuse element is bonded to a ceramic substrate and  
encapsulated with glass, providing excellent short-circuit  
performance and environmental integrity. Predicted reliability  
of the 1608FF chip fuse is 30 times greater than that of the  
typical chip capacitor (consult Bussmann for details).  
Substrate and coating thermal expansion coefficients are  
closely matched to that of FR-4 epoxy-glass circuit board for  
superior solder joint reliability.

General Notes:  
1. AC interrupting rating, melting integral and total clearing integral measured at 32V, unity power factor.  
2. DC interrupting rating, melting integral and total clearing integral measured at 63V (250mA-3A) and 32V (4-5A), with a battery source.  
3. It is recommended that fuses be mounted with ceramic (white) side facing up.  
4. Contact Bussmann if higher ampere ratings are needed.  
5. 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.
