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

Solder
reflow
※ Due to
“Lead Free” nature, Temperature and Dwelling time for the
soldering zone is higher than those for Regular. This may
cause damage to other components.
1. Recommended max past thickness > 0.25mm.
2. Devices can be cleaned using standard methods and
aqueous solvent.
3. Rework use standard industry practices.
4. Storage Environment : < 30℃ /
60%RH
Caution:
1. If reflow temperatures exceed the recommended profile,
devices may not meet the performance requirements.
2. Devices
are not designed to be wave soldered to the bottom side of the
board.
