Manual Soldering Recommendation Parameters
Items
Soldering condition
Conditions
The highest power of the manual soldering iron should be 30W or less, soldering
temperature should not be higher than 280℃.
The soldering time should be kept within 3 seconds, otherwise it might cause
insulation layer cracking, and increased part resistance.
The distance on the leads between the soldering point and bottom of the PPTC
body should be equal or greater than 4mm.
The soldering iron should not contact the PPTC body except the leads. If the
soldering conditions are kept to lower temperature, less time and larger distance,
the outcome of the soldering will be better.

Notes: 1. Before using the device must be stored in the original bags, if the storage conditions do not guarantee,
the device may not be able to meet the given value.
2. The devices can’t used for reflow soldering.
