It is rated for 32 V AC and 65 V DC, with a breaking capacity of 35 A AC and 13 A DC at the rated voltage. The 1.25 A current rating sets the threshold where the fuse element begins to melt under sustained overload. The fast-blow response means it clears quickly on short-circuit events, limiting peak let-through energy to 0.0518 A²s (melting I²t). ## Breaking capacity and coordination With a breaking capacity of 35 A AC and 13 A DC, this fuse can safely interrupt fault currents up to those levels without rupturing. The 0.0518 A²s melting I²t is the energy required to open the fuse — this value is used to coordinate with downstream semiconductor or PCB trace fusing. The DC cold resistance of 0.051 Ohms at 25°C produces a voltage drop of about 64 mV at rated current — negligible in most low-voltage circuits but worth checking if the load is sensitive to supply droop. ## Approvals and operating range The 04671.25NRHF carries CSA and UL approvals, certifying compliance with North American safety standards for overcurrent protection. The operating temperature range spans -55°C to 90°C, covering most industrial control, telecom, and automotive under-hood environments.","metaTitle":"04671.25NRHF Littelfuse 467 Series 1.25 A Fast Blow Fuse","metaDescription":"Littelfuse 04671.25NRHF 467 Series 1.25 A fast-blow surface-mount fuse, 32 VAC / 65 VDC, 0603 package.
