The 45 A interrupting rating means this fuse can safely clear a fault current up to that level without rupturing or sustaining an arc — critical for protecting downstream traces and components in a 24 V power distribution bus. ## Melting I²t and coordination for secondary-side protection With a melting I²t of 1.75, this fuse coordinates with downstream semiconductor ratings — the energy let-through stays below the surge capability of typical Schottky rectifiers and DC-DC converter input stages on a 24 V rail. The fast-blow response time suits applications where the load inrush is minimal and the fuse must open quickly on a hard short — secondary-side protection in DC-powered equipment, instrumentation, or battery-management circuits. ## Obsolete — sourcing through independent channels Littelfuse has marked the 1206SFF700F/32-2 as obsolete. For existing BOM lines, this part is available through independent surplus and broker channels. ## UL recognized — compliance basis for equipment certification The fuse carries UL recognition, which certifies that the construction and performance meet UL 248-14 for supplemental fuses — a prerequisite for UL 60950 or UL 62368 end-equipment safety certification. Operating temperature range spans -55°C to 125°C, covering industrial and automotive under-hood ambient conditions without derating the current rating at the upper end. ## 1206 footprint — board layout and reflow profile The DC cold resistance of 0.011 ohms keeps voltage drop below 80 mV at rated current — negligible in a 24 V rail.","metaTitle":"Littelfuse 1206SFF700F/32-2 7A Fast Blow Fuse, 24V","metaDescription":"Littelfuse 1206SFF700F/32-2 7A fast-blow surface-mount fuse, 24V DC, 45A breaking capacity, UL recognized.
