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.
