Requirements of mobile phone market for fuse are as follows:

1.  Light, thin, short and small mobile phone has been the development trend of mobile phone market, which requires that the component size shall be smaller and smaller; 

2.  With more and more functions and lower and lower power consumption, mobile phone is powered by lithium batteries, so the internal resistance of fuse shall be smaller;

3.  Pulse current of mobile phone is low and working current is small, so FUSE shall implement quick fuse to ensure safety.

SARTFUSE applies to overcurrent protection of mobile phone power management.
