Description
The 501 Series is a 100% Lead-free, RoHS compliant and
Halogen-free fuse series designed specifically to provide
over- current protection to circuits that operate under high
working ambient temperature up to 150°C.
The general design ensures excellent temperature stability
and performance reliability.
The high I
Ceramic Fuse family, ensure high inrush current withstand
capability.
