Fuse Datasheet 466 Series 1206 Fast-Acting Fuse RoHS Pb Description The 466 Series Fast-Acting Surface Mount Fuse (SMF) is a small (1206 size) thin-film device designed for secondary protection of circuits used in space constrained applications such as hand-held portable electronic devices. This series is 100% lead-free and meets the requirements of the RoHS directive. New Halogen-Free 466 Series fuses are available to order using the HF suffix. See Part Numbering section for additional information. Features & Benefits Product is compatible with Flat top surface for pick-and- lead-free solders and higher place operations temperature profiles Element-co vering material is Product is marked on top resistant to industry standard surface with code to allow cleaning operations amperage rating identification L ead-free, Halogen-free and without testing Additional Information RoHS compliant L ow profile for height sensitive Recognized to UL/CSA/NMX applications 248-1 and UL/CSA/NMX 248- 14 Applications Secondary protection for space constrained applications: Resources Accessories Samples Cell phones DVD players Battery packs Hard disk drives Digit al cameras Electrical Characteristics for Series Agency Approvals O Agency Agency File Number Ampere Range % of Ampere Rating Opening Time at 25 C 100% 4 hours, Minimum E10480 0.125A - 5A 200% 5 sec., Maximum 29862 0.125A - 5A 300% 0.2 sec., Maximum Electrical Specifications by Item Agency Approvals Max Nominal Cold Nominal Nom Nom Power Ampere Rating Amp Interrupting Voltage Rating Resistance Melting Voltage Drop Dissipation (A) Code Rating 2 2 (V) (Ohms) I t (A sec) (mV) (W) 0.125 .125 125 3.925 0.00064 634.37 0.0793 x x 0.200 .200 125 50A 125VAC/ 1.100 0.00055 254.28 0.0509 x x VDC 0.250 .250 125 0.691 0.0022 207.01 0.0518 x x 0.375 .375 125 0.351 0.0045 169.18 0.0634 x x 0.500 .500 63 0.248 0.0060 158.47 0.0792 x x 0.750 .750 63 0.106 0.0276 98.65 0.0740 x x 1.00 001. 63 0.075 0.0423 79.97 0.0800 x x 1.25 1.25 63 50A 63VAC/VDC 0.057 0.0640 85.71 0.1071 x x 1.50 01.5 63 0.046 0.1103 82.97 0.1244 x x 1.75 1.75 63 0.038 0.1835 80.73 0.1413 x x 2.00 002. 63 0.030 0.2326 78.73 0.1575 x x 2.50 02.5 32 0.023 0.3516 76.99 0.1925 x x 3.00 003. 32 0.019 0.5760 75.99 0.2280 x x 50A 32VAC/VDC 4.00 004. 32 0.014 1.764 74.50 0.2980 x x 5.00 005. 32 0.011 2.500 73.75 0.3688 x x 1.

Re-rating depicted in this curve is in addition to the standard re-rating of 25% for continuous operation. Example: For continuous operation at 70 degrees celsius, the fuse should be rerated as follows: I = (0.75)(0.80)I = (0.60)I RAT RAT 0.01 2.
