Series 467 board-mount fast-blow fuse, 046701.5NRHF, 1.5 A, 32 VAC / 65 VDC, 0.0385 Ω cold resistance, 0603 (1608 metric) SMD package, CSA and UL approved.","salesMarkdown":"## 1.5 A fast-blow protection in a 0603 footprint The Littelfuse 046701.5NRHF is a 1.5 A fast-blow board-mount fuse from the 467 series, packaged in a 0603 (1608 metric) SMD format. It is designed for surface-mount assembly and provides overcurrent protection on compact PCBs where space is at a premium. Rated for 32 VAC and 65 VDC, this fuse handles typical low-voltage rail protection in telecom, industrial control, and consumer electronics — the 65 VDC rating covers 48 V telecom bus applications with margin. ## Breaking capacity and let-through energy Breaking capacity is 35 A at rated AC voltage and 13 A at rated DC voltage — sufficient for interrupting fault currents in most secondary-side power circuits where the upstream supply is a limited-current source. Melting I²t of 0.0766 A²s defines the energy the fuse passes before clearing. This value is critical for coordinating with downstream semiconductor protection — a lower I²t reduces stress on the protected device during a fault. DC cold resistance of 0.0385 Ω at 25 °C means the fuse drops about 58 mV at rated current and dissipates roughly 87 mW — negligible for most PCB thermal budgets but worth checking in high-density layouts where local heating compounds. ## Approvals and compliance Operating temperature range spans -55 °C to 90 °C, covering standard industrial and commercial environments. The upper limit is below the 125 °C automotive grade, so this fuse is suited for controlled indoor or outdoor enclosures rather than under-hood or engine-bay deployment.","metaTitle":"Littelfuse 046701.5NRHF 467 Series, 1.5 A Fast-Blow Fuse","metaDescription":"Active Littelfuse 046701.5NRHF 1.5 A fast-blow board-mount fuse, 0603 SMD, 32 VAC / 65 VDC, 0.0385 Ω cold resistance.
