Warning for Reflow:
1、The printed solder thickness is not over 0.25mm,Excess
solder may cause a short circuit, especially during hand soldering
2、If reflow temperatures exceed the recommended profile,
devices may not meet the performance requirements
3 、 Device can not be wave soldered. Please contact TLC for
hand soldering and dip soldering recommendations.
4、Device can’t contact solvent
Note:All temperature in top chart is measured on the surface of devices

Cautions for SMD PPTC Use
Operation beyond the rated maximum voltage or current may result in device damage and possible electrical
arcing
or flame.
Hold current at all temperatures specified in the SPEC is the conventional performance of PTC obtained by one
time
reflow welding. PTC can hold 1 hour under current conditions at a given temperature. This current is not the
condition
of long-term charging or discharging current for this type of PTC.
The above parameters are concluded from one time of reflow soldering processing the PTC. If there is any
further heat generated process like injection or dispensing at the customer's premise, the aforementioned
parameters will decrease
at certain degree. Therefore the verification test to be conducted is necessary.
The PTC is thermal sensitive device. It is recommended not to design any heat source devices around it to
reduce the outside heat source impact.
SMD PTC is designed for SMT processing which applies reflow soldering. Please refer to the recommended
solder reflow curve. If the reflow soldering temperature exceeds the recommended value, the PTC might be
damaged. Hand welding PTC is prohibited. Heat gun is not allowed to use during the circuit board components
or terminals rework .
Please do not smash, clamp, pull, dent or twist by tool during assembling process otherwise it might be a
cause of the performance degradation.
PTC is resettable protection device which shall not be taken for use as switch. Multiple times tripping
shall lower the PTC hold current.
In the process of PTC processing, if there is soldering iron welding process, it is suggested that the
welding position
should be more than 1.5mm away from PTC, the welding tool temperature should be lower than 350 ℃, and the
contact
time between soldering iron and solder joint should not exceed 3sec.
