Wave Solder Proļ¬le
Because the TMOVĀ® and iTMOVĀ® varistors contain a thermal protection device, care must be taken when soldering the devices into place.
Two soldering methods are possible. Firstly, hand soldering: It is recommended to heat-sink the leads of the device. Secondly, wave solder-
ing: It is critically important that all preheat stage and the solder bath temperatures are rigidly controlled.
