※

Perform adequate test in advance as the reflow temperature profile will vary according to the conditions of the

manufacturing process, and the specification of the reflow furnace.

5.5 Resistance to soldering heat-High Temperature Resistance:260

5.6 Hand Soldering

℃,10sec-3times.

In hand soldering of the Varistors. Large temperature gradient between preheated the Varistors and the tip of

soldering iron may cause electrical failures and mechanical damages such as crackings or breakings of the

devices. The soldering shall be carefully controlled and carried out so that the temperature gradient is kept

minimum with following recommended conditions for hand soldering.

5.6.1 Recommended Soldering Condition 1

（1） Solder ：

0.12~0.18mm Thread solder (Sn96.5:Ag3.5) with soldering flux in the core. Rosin-based and

non-activated flux is recommended.

（2） Preheating

The Varistors shall be preheated so that Temperature Gradient between the devices and the tip of

soldering iron is 150℃ or below.
