Product details

Obsolete — sourcing path for a 10 A 24 V fast-blow

The 1206SFH100F/24-2: Sourcing is confirmed against an RFQ — quantities and pricing are lot-specific and quoted at order time.

What the 10 A rating and 100 A breaking capacity mean for your circuit

Rated 10 A at 24 V DC, this fuse is sized for a continuous load current at or below 10 A in a 24 V DC rail. The 100 A interrupting rating at 24 V DC means it can safely clear a fault up to 100 A without rupturing or sustaining an arc — this is the key parameter for ensuring the fuse clears a short circuit before the PCB trace or downstream components fail. The fast-blow response time means it opens quickly on overcurrent, protecting sensitive semiconductor loads that cannot tolerate even a few milliseconds of sustained fault current. A melting I²t of 9 A²s gives a measure of the energy needed to blow the fuse — useful for coordinating with upstream protection and for estimating let-through energy during a fault.

Package and board-fit for the 1206 footprint

The 0.01 Ohm DC cold resistance means minimal voltage drop and power dissipation at rated current — about 1 W at 10 A, which the 1206 footprint can handle with adequate copper pad area. The UL approval confirms the fuse meets the UL 248 standard for branch-circuit protection.

Frequently asked questions

Where can I buy the 1206SFH100F/24-2 and check stock?

Submit an RFQ for lot-specific quantities and lead time.

What is the breaking capacity of the 1206SFH100F/24-2?

The breaking capacity at the rated voltage of 24 V DC is 100 A. This means the fuse can safely interrupt a fault current up to 100 A without rupturing or sustaining an arc.

What compliance documentation does Littelfuse provide for the 1206SFH100F/24-2?

The fuse carries UL approval, confirming it meets the UL 248 standard for branch-circuit protection.
