Surface Mount Fuses NANO2® > Slo-Blo® Fuse > 452/454 Series 452/454 Series Fuse RoHS PS E Description The NANO2® Slo-Blo® fuse has enhanced inrush withstand characteristics over the NANO2® Fast-Acting fuse. The unique time delay feature of this fuse design helps solve the problem of nuisance “opening” by accommodating inrush currents that normally cause a fast-acting fuse to open. Features • Small size • UL Recognized to UL/ CSA/NMX UL 248-1 and • Wide range of current rating available (0.375A UL/CSA/NMX UL 248-14 to 12A) • Conforms to DENAN’s Agency Approvals • Wide operating Appendix 3 temperature range Agency Agency File Number Ampere Range • RoHS compliant and Halogen Free E10480 0.375A - 12A 29862 0.375A - 12A PS NBK030205-E10480B 1A - 5A Applications E • Notebook PC • Storage system • LCD/PDP TV • Telecom system Electrical Characteristics for Series • LCD monitor • Wireless basestation • LCD/PDP panel • White goods % of Ampere Rating Opening Time • LCD backlight inverter • Game console • Portable DVD player • Office Automation 100% 4 hours, Minimum equipment 200% 1 sec., Min.; 60 sec., Max. • Power supply • Battery charging circuit 300% 0.2 sec., Min.; 3 sec., Max • Networking protection 800% 0.002 sec., Min.; 0.1 sec., Max. • PC server • Industrial equipment • Cooling fan system Electrical Specifications by Item Max Agency Approvals Ampere Rating Interrupting Nominal Cold Nominal Melting Amp Code Voltage Rating (A) Rating Resistance (Ohms) I2t (A2sec) PS (V) E 0.375 .375 125 1.2000 0.101 x x 0.500 .500 125 0.7000 0.240 x x 0.750 .750 125 0.3600 0.904 x x 001. 001. 125 0.2250 1.98 x x x 1.50 01.5 125 50A @ 125 VAC/VDC 0.0930 3.65 x x x 2.00 002. 125 300A @ 32 VDC 0.0625 8.20 x x x 2.50 02.5 125 PSE: 100A @ 100 VAC 0.0450 15.0 x x x 3.00 003. 125 0.0340 20.16 x x x 3.50 03.5 125 0.0224 26.53 x x x 4.00 004. 125 0.0186 34.40 x x x 5.00 005. 125 0.0136 53.72 x x x 7.00 007. 75 50A @ 72 VAC 0.0105 123.83 x x 8 008. 75 50A @ 60 VDC 0.0088 137.34 x x 12 012. 75 100A @ 75 VDC 0.0061 260.46 x x Notes: - l2t calculated at 8ms. - Resistance is measured at 10% of rated current, 25ºC © 2019 Littelfuse, Inc.
