Surface Mount Fuses 2 NANO Fuse > 250V > Fast Acting > 476 Series PS RoHS E 476 Series Fuse Description The 476 Series is a family of 250V rated fuses with a very small 2410 footprint. It is the smallest SMD fuse with this high voltage rating and is designed to mainly serve as primary side circuit protection for compact devices with high voltage requirements. Features Small 2410 Footprint IEC 61547 Surge Compliant (tested per IEC 61000-4-5 250V Voltage Rating (1A to with a combination wave of 5A) 500V, 1.2/50us and 250A, High Interrupting Ratings 8/20us for 25W Luminaires) Agency Approvals Fast-Acting only for 3A and above RoHS Compliant and Agency Agency File Number Ampere Range Halogen-Free Wide Operating temperature E10480 1A - 15A range of -55C to 125C NBK240818-JP1021A 1A - 1.6A PS E NBK240818-JP1021B 2A - 5A Electrical Characteristics for Series Applications % of Ampere LED Lighting Power Supply Units Ampere Rating Opening Time Rating LCD/LED TVs White Goods 100% 1A - 15A 4 Hour, Minimum 125% 1A - 5A 1 Hour, Minimum 200% 1A - 15A 120 Sec., Maximum 1000% 1A - 5A 0.001 Sec., Min 0.01 Sec., Max Electrical Characteristic Agency Approvals Ampere Nominal Max Voltage Nominal Melting Rating Amp Code Interrupting Rating Cold Resistance 2 2 Rating (V) I t (A sec.)
