SFH series, board mount fast blow fuse, 1206 (3216 Metric) surface mount package, 20 A, 24 V DC, 100 A breaking capacity, UL approved.","salesMarkdown":"## SFH series 20 A fast-blow fuse The Littelfuse 1206SFH200F/24-2 is a 20 A, 24 V DC fast-blow fuse from the SFH series, designed for surface-mount board-level overcurrent protection. Rated breaking capacity of 100 A at the rated voltage means it can safely interrupt a fault current up to that level without rupturing or sustaining an arc. ## Parametric fit and board integration The 1206 (3216 Metric) footprint is a common surface-mount fuse package, allowing direct replacement on existing PCB layouts that accept this standard size. With a DC cold resistance of 0.003 ohms, voltage drop across the fuse at rated current is negligible — about 60 mV — minimizing power dissipation in high-current paths. Melting I²t of 56 provides the energy let-through characteristic needed for selective coordination with downstream components in a protection scheme. ## Sourcing and lifecycle reality UL approval is on file, supporting compliance with North American safety standards for the original design.","metaTitle":"Littelfuse 1206SFH200F/24-2 Fuse, 20A, 24V DC, Fast Blow","metaDescription":"Littelfuse 1206SFH200F/24-2 SFH series fuse, 20 A, 24 V DC, fast blow, 100 A breaking capacity, UL approved.
