Obsolete — sourcing through independent channels
The 1206SFP600F/24-2: For a BOM line that still calls out this exact Littelfuse SFP series part, the supply path runs through independent surplus and excess inventory channels. Availability is lot-specific and confirmed at the time of an RFQ — no standing stock is held.
6 A at 24 VDC — what the ratings mean for fit
Rated 6 A continuous at 24 VDC with a breaking capacity of 50 A at that voltage. The 50 A interrupt rating means the fuse clears a fault current up to that level without rupturing the 1206 ceramic body — adequate for low-voltage DC rails in control boards, battery management circuits, and point-of-load protection where the available fault current stays under 50 A. Melting I²t is 12.5 A²s — this is the energy needed to open the element. For inrush-prone loads (capacitive input filters, motor start windings), the I²t must exceed the surge energy or the fuse will nuisance-blow. The 0.013 Ohm cold resistance keeps voltage drop under 80 mV at rated current, which matters for low-voltage rails where every millivolt counts.
1206 surface-mount — board integration
Reflow soldering profile follows the standard JEDEC J-STD-020 for a ceramic body; no special pad geometry beyond the datasheet recommendation is needed. Operating temperature range is -55°C to 125°C, covering the full industrial and automotive ambient envelope. The fuse is a board-mount type (cartridge style excluded), meaning it is designed for direct PCB soldering rather than a clip or holder.
