IT=Trip current-maximum current at which the device will always trip at 23°C still air. V MAX=Maximum voltage device can withstand without damage at its rated current (I MAX). I MAX=Maximum fault current device can withstand without damage at rated voltage (V MAX). Pd=Typical power dissipated-type amount of power dissipated by the device when in the tripped state in 23°C still air environment. R MIN=Minimum device resistance at 23°C prior to tripping. R1MAX=Maximum device resistance at 23°C measured 1 hour post trip.

Recommended reflow methods; IR, vapor phase oven, hot air oven. 2. The FSMD Series are suitable for use with wave-solder application methods. (Top side only) 3. Recommended maximum paste thickness is 0.25mm. 4. Devices can be cleaned by using standard industry methods and solvents. 5. Storage Environment: <30°C / 60%RH Caution: If reflow temperatures exceed the recommended profile, devices may not meet performance requirements. Rework: Use standard industry practices.
