Its 35 A breaking capacity at rated voltage means it can safely interrupt a fault current up to that level without rupturing the package — critical for secondary-side protection in DC power rails where the available fault current stays below that ceiling. ## Energy let-through and coordination With a melting I²t of 0.73 A²s, this fuse lets through a defined amount of energy before opening. Downstream components — traces, connectors, semiconductors — must survive that pulse without damage; the I²t value feeds directly into the coordination math for a DC supply rail. The DC cold resistance of 0.028 Ohms sets the voltage drop at rated current at roughly 98 mV — negligible in a 32 V rail, but worth confirming against the minimum operating voltage of the load at the end of the trace. The UL approval certifies the safety compliance for the rated interrupting capacity — a requirement for passing the end-equipment safety certification in most jurisdictions. ## Lifecycle reality and sourcing posture Littelfuse has marked the 0603SFV350F/32-2 as obsolete.","metaTitle":"Littelfuse 0603SFV350F/32-2 Fuse, 3.5A, 32V, Fast Blow","metaDescription":"Littelfuse 0603SFV350F/32-2 SFV series board mount fuse, 3.5 A, 32 VDC, fast blow, 35A breaking capacity, UL approved.
