Surface Mount Fuses  
Ceramic Fuse > 437 Series  
437 Series – 1206 Fast-Acting Fuse  
Description  
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.

Notes:  
1. AC Interrupting Rating tested at rated voltage with unity power factor. DC Interrupting  
Devices designed to carry rated current for 4 hours minimum. It is recommended that  
devices be operated continuously at no more than 80% rated current. See “Temperature  
Rerating Curve”for additional rerating information.  
Rating tested at rated voltage with time constant < 0.8 msec.  
2. Nominal Resistance measured with < 10% rated current.  
3. Nominal Melting I²t measured at 1 msecs. opening time.  
Devices designed to be mounted with marking code facing up.  
4. Nominal Voltage Drop measured at rated current after temperature has stabilized.
