Product details

12 A fast-blow for 24 VDC rails

The Littelfuse 1206SFH120F/24-2 is a 12 A, 24 VDC fast-blow fuse in the SFH series, designed to clear faults on low-voltage DC power rails where a quick open time protects downstream silicon from prolonged overcurrent. Its 100 A breaking capacity at 24 VDC means it can safely interrupt a hard short without arcing through the 1206 package — a requirement for UL-recognized board-level protection in power-distribution and battery-management circuits.

Obsolete — sourcing through independent channels

No pin-compatible drop-in replacement exists from Littelfuse, so a BOM revision or board spin may be needed for long-term production.

Frequently asked questions

What is the melting I²t of the 1206SFH120F/24-2?

The melting I²t is rated at 14, which determines how much energy the fuse absorbs before opening — useful for sizing against inrush current from capacitive loads on the 24 V rail.
