This means the manufacturer no longer produces it, and the only supply channel is independent surplus or broker inventory. For a BOM that needs a drop-in replacement, a board spin or a parametric search within the SFV series may be required — the 0603 footprint and 5 A / 32 V DC rating are the binding constraints. ## 5 A fast-blow in a 0603 body Rated 5 A continuous at 32 V DC with a 35 A breaking capacity at rated voltage. The 35 A interrupt rating means it safely clears a fault current up to that level without rupturing the 0603 ceramic body — adequate for secondary-side protection in DC power rails where the available fault current stays under that ceiling. Fast-blow response time means the fuse element opens quickly on overcurrent, suited for protecting sensitive semiconductor loads that cannot tolerate even brief overcurrent stress. The melting I²t of 2.62 quantifies the energy needed to clear the fuse — useful for coordinating with downstream components and ensuring the fuse blows before the protected device fails. This resistance also sets the voltage drop the load sees under normal operation. ## 0603 surface-mount and UL recognition Housed in a standard 0603 (1608 Metric) package for surface-mount assembly. The 0.063\" x 0.031\" footprint matches the common chip resistor and capacitor land pattern, so no special pad geometry is needed — pick-and-place and reflow are straightforward. UL recognized — the fuse carries an approval mark accepted in North American equipment.","metaTitle":"0603SFV500F/32-2 Littelfuse SFV 5A 32V Fast Blow Fuse","metaDescription":"0603SFV500F/32-2 Littelfuse SFV series 5A 32V DC fast-blow board mount fuse, 0603 package, 35A breaking capacity.
