I trip = Trip current: minimum current at which the device will trip in 25°C still air. V max = Maximum voltage device can withstand without damage at rated current (I max) I max = Maximum fault current device can withstand without damage at rated voltage (V max) P d = Power dissipated from device when in the tripped state at 25°C still air. 1 Document Number: P170702J1154 R min = Minimum resistance of device in initial (un-soldered) state. R typ = Typical resistance of device in initial (un-soldered) state. R 1max = Maximum resistance of device at 25°C measured one hour after tripping or reow soldering of 260°C for 20 sec. Operating Temperature = -40 °C to +85 °C Surface-Mount Devices | 0603 Size SRF0603 Series PTC Resettable Fuses Thermal Derating Chart Hold Current (A) Ambient Operating Temperature Part Number -40°C -20°C 0°C 25°C 40°C 50°C 60°C 70°C 85°C SRF0603P010 0.13 0.12 0.11 0.10 0.08 0.07 0.06 0.05 0.03 SRF0603P020 0.27 0.25 0.23 0.20 0.17 0.14 0.12 0.10 0.07 SRF0603P035 0.47 0.41 0.38 0.35 0.29 0.26 0.24 0.20 0.14 SRF0603P050 0.67 0.60 0.54 0.50 0.41 0.37 0.34 0.29 0.20 Temperature Rerating Curve 170% Percentage of Rated Current 150% 130% 110% 90% 70% 50% 30% 10% -40 -30 -20 -10 0 10 20 30 40 50 60 70 80 Temperature (°C) Dimensions (mm) A Top View B C Recommended Pad Layout (mm) Side View 0.80 1.00 Bottom View 1.00 D Part Number Marking A Min.
