Warning:
  1. Operation beyond the specified maximum ratings or improper use may result in damage and possible electrical arcing and/or flame.
  2. PPTC device are intended for occasional overcurrent protection. Application for repeated overcurrent condition and/or prolonged trip are not anticipated.
  3. Avoid contact of PPTC device with chemical solvent. Prolonged contact will damage the device performance.

 Solder reflow
Due to “Lead Free” nature, up to 40 seconds Dwelling time for the soldering zone is strongly recommend .
1. Recommended reflow methods; IR, vapor phase oven, hot air oven.
2. The FSMD1812 Series are suitable for use with wave-solder application methods.
3. Recommended maximum paste thickness is 0.25mm.
4. Devices can be cleaned using standard industry methods and solvents.

CAUTION:
If reflow temperatures exceed the recommended Profile, devices may not meet the performance requirements.

Rework:
Use standard industry practices.

All the specifications are subject to change without previous notice.
