EBF Fuse •RoHS Pb
Fast-Acting Type 447 Series
Through-hole version of the 446P series.
®
®
ELECTRICAL CHARACTERISTICS: Same as 446P Series.
Dimensions: Contact Littelfuse for specifications.
Soldering Parameters: Contact Littelfuse for soldering parameters.
Inside terminal face of each lead is non-plated zinc. Non-plated zinc
terminal faces may not meet MIL-STD-202, method 208. To ensure that
the fuse is acceptable for the application, appropriate application testing
should be performed.
