Surface Mount Fuses  
Ceramic Fuse > 437A Series  
RoHS Pb  
437A Series – 1206 Fast-Acting Ceramic Fuse  
Description  
The 437A Series AECQ-Compliant fuses are specifically  
tested to cater to secondary circuit protection needs of  
compact auto-electronics applications.  
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  
• OperatingTemperature  
from -55ºC to +150ºC  
• Fast response to faulty  
current to ensure over-  
current protection for  
sensitive electronic  
components  
• 100% Lead-free, Halogen-  
Free and RoHS compliant

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  
Re-rating Curve”for additional re-rating information. Devices designed to be mounted with  
marking code facing up.  
Notes:  
1. AC Interrupting Rating tested at rated voltage with unity power factor. DC Interrupting  
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 msec. opening time.  
© 2017 Littelfuse, Inc.  
Application testing is strongly recommended. Specifications are subject to change without notice.  
Revised: 11/16/17  
4. Nominal Voltage Drop measured at rated current after temperature has stabilized.
