Very Fast-Acting Ceramic Fuse
Fuse_437_Datasheet.pdf
This 100% Lead-free, RoHS compliant and Halogen-free fuse series
has been designed specifically to provide over current protection
to circuits that see high working ambient temperatures (up to
150ºC). The general design ensures excellent temperature stability
and performance reliability. In addition to this, the high I²t
values typical of the Littelfuse Ceramic Fuse family ensure high
inrush current withstand capability.
Features
• Operating Temperature from -55ºC to +150ºC
• 100% Lead-free, HalogenFree and RoHS compliant
• Suitable for both leaded and lead-free reflow / wave soldering
Applications
LCD Displays • Servers • Printers • Scanners • Data Modems
