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 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 Agency Approvals • Operating Temperature • Suitable for both leaded from -55ºC to +150ºC and lead-free reflow / AGENCY AGENCY FILE NUMBER AMPERE RANGE • 100% Lead-free, Halogen- wave soldering Free and RoHS compliant E10480 0.250A ~ 8A Applications 29862 0.250A ~ 8A • LCD Displays • Scanners • Servers • Data Modems Electrical Characteristics for Series • Printers % of Ampere Ampere Rating Opening Time at 25ºC Rating Additional Information 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 Agency Approvals Ampere Max.
