Wave Solder Profile
Because the TMOV25S™ Series contains a thermally
responsive device, care must be taken when soldering
the device into place. Two soldering methods are possible.
Firstly, hand soldering: We recommend the use of pliers
to heat-sink the leads of the device. Secondly, wave-
soldering: This is a strenuous process requiring pre-heat
stages to reduce the stresses on devices.
It is critically important that all preheat stage and the
solder bath temperatures are rigidly controlled. The
recommended solder for the TMOV
(Sn/Pb/Ag), 60/40 (Sn/Pb) or 63/37 (Sn/Pb). Littelfuse also
recommends an RMA solder flux. SAC solders (SnAgCu)
are recommended for Lead-free applications.
