Description  
The 434 series fast-acting surface mount fuse series is  
an ultra small (0603 size) thin-film device designed for  
secondary protection of circuits used in space constrained  
applications such as hand-held portable electronic devices.  
For RoHS compliant and lead-free design, please refer to  
the Littelfuse 467 series thin film fuse.  
Features  
tꢀ 5IFꢀ4MJN-JOFꢀꢁꢂꢁꢃꢀ  
fuse is an extremely  
tꢀ 5IFꢀMPXFSꢀIFJHIUꢀQSPmMFꢀ  
produces a flat surface for  
improved performance in  
pick-and-place operations  
and an alternate solution  
for height critical  
small, low profile design  
(0603 chip size) utilizing  
thin-film technology to  
achieve precise control of  
electrical characteristics.
