IT: Tripping current, minimum current at which the device from low resistance to high resistance in 25°C still air. VMAX: Maximum continuous voltage device can withstand without damage at rated current. IMAX: Maximum fault current device can withstand without damage at rated voltage. Maximum Time-to-trip: Maximum time to trip at assigned current. Pd: Typical amount of power dissipated from the device when in 25°C still air environment. RiMin: Minimum resistance of device at 25°C prior to tripping. R1Max: Maximum resistance of device is measured one hour post reflow. ## **Thermal Derating Chart-IH (A)** |**Part Number**|**Maximum holding current at assigned ambient temperature(A)**|**Maximum holding current at assigned ambient temperature(A)**|**Maximum holding current at assigned ambient temperature(A)**|**Maximum holding current at assigned ambient temperature(A)**|**Maximum holding current at assigned ambient temperature(A)**|**Maximum holding current at assigned ambient temperature(A)**|**Maximum holding current at assigned ambient temperature(A)**|**Maximum holding current at assigned ambient temperature(A)**|**Maximum holding current at assigned ambient temperature(A)**| |---|---|---|---|---|---|---|---|---|---| ||**-40°C**|**-20°C**|**0°C**|**25°C**|**40°C**|**50°C**|**60°C**|**70°C**|**85°C**| |MP001612|0.23|0.19|0.17|0.14|0.12|0.1|0.09|0.08|0.06| Newark.com/multicomp-pro Farnell.com/multicomp-pro Element14.com/multicomp-pro Page <1> 16/12/19 V1.0 ## **Surface Mount PPTC Fuse 1812** ## **Physical Characteristics** |Terminal Pad Materials|Tin-Plated Nickle-copper| |---|---| |SolderingCharacteristics|EIA specification RS 186-9E, ANSI/J-STD-002| |Moisture Sensitivity|Level 2a,per IPC/JEDEC J-STD 020C| ## **Environmental Specifications** |**Test Item**|**Test Conditions**|**Resistance Change**| |---|---|---| |Storage life|85°C,1000 hours|±10% typical| |HumidityAging|85°C/85%RH.100 hours|±5% typical| |Thermal Shock|MIL-STD-202, Method 107G
