1.1
Leaded thermistors comply with the solderability requirements specified by CECC.
When soldering, care must be taken that the NTC thermistors are not damaged by excessive
heat. The following maximum temperatures, maximum time spans and minimum distances have
to be observed:
Bath temperature
Soldering time
Distance from thermistor
Under more severe soldering conditions the resistance may change.
Solderability (test to IEC 60068-2-58)
Preconditioning: Immersion into flux F-SW 32.
Evaluation criterion: Wetting of soldering areas 95%.
Solder
SnAg (3.0 ... 4.0), Cu (0.5 ... 0.9)
1.1.1
Preconditioning: Immersion into flux F-SW 32.
