Surface Mount Fuses Ceramic Fuse > 469 Series 469 Series – 1206 Slo-Blo® Fuse RoHS Pb Description The 469 Series is a 100% Lead-free, RoHS compliant and Halogen-free fuse series designed specifically to provide over-current protection to circuits that operate under high working ambient temperature up to 150ºC. The general design ensures excellent temperature stability and performance reliability. The high I²t values, typical in 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, RoHS compliant and Halogen- AGENCY AGENCY FILE NUMBER AMPERE RANGE free E10480 2A – 8A Applications 29862 2A – 8A • LCD Displays • Scanners • Servers • Data Modems Electrical Characteristics for Series • Notebook Computers • Gaming Consoles • Printers % of Ampere Ampere Opening Time at 25ºC Rating Rating 100% 2A – 8A 4 hours, Minimum Additional Information 200% 2A – 8A 1 sec., Min.; 120 secs., Max. 300% 2A – 8A 0.1 sec., Min.; 3 secs., Max. 800% 2A – 8A 0.002 sec., Min.; 0.05 sec., Max.

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 Rating tested at rated voltage with time constant < 0.8 msec. devices be operated continuously at no more than 80% rated current. See “Temperature Re-rating Curve”for additional re-rating information. 2. Nominal Resistance measured with < 10% rated current. 3. Nominal Melting I²t measured at 1 msec opening time. Devices designed to be mounted with marking code facing up. 4. Nominal Voltage Drop measured at rated current after temperature has stabilized. © 2018 Littelfuse, Inc.
