Surface Mount Fuses Ceramic Fuse > 437 Series 437 Series – 1206 Fast-Acting Fuse RoHS Pb Description This 100% Lead-free, RoHS compliant and Halogen-free fuse series has been designed specifically to provide over current protection to circuits might encounter 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 • Suitable for both leaded from -55ºC to +150ºC and lead-free reflow / Agency Approvals wave soldering • 100% Lead-free, Halogen- Agency Agency File Number Ampere Range Free and RoHS compliant • UL Recognized to UL/ CSA/NMX 248-1 and UL/ E10480 0.250A - 8A CSA/NMX 248-14 29862 0.250A - 8A Applications • LCD Displays • Scanners • Servers • Data Modems • Printers Electrical Characteristics for Series % of Ampere Ampere Rating Opening Time at 25ºC Additional Information Rating 100% 250mA - 8A 4 hours, Minimum 250% 750mA - 8A 5 seconds, Maximum 350% 250mA -500mA 5 seconds, Maximum 350% 750mA - 8A 1 second, Maximum Datasheet Resources Samples Electrical Specifications by Item Ampere Max.
