Surface Mount Multilayer Varistor
SC0402E - SC0603E Series
Description
The SC Series is based on Multilayer fabrication technology.
These components are designed to suppress a variety of
transient events, including those specified in IEC 61000-4-2 or
other standards used for Electromagnetic Compliance (EMC).
The SC Series is typically applied to protect integrated circuits
and other components at the circuit board level. It can operate
over a wider temperature range than zener diodes.

Precaution for handling of substrate
Do not exceed to bend the board after soldering thes product
extremely. (reference examples)
l
Mounting place must be as far as possible from the
position, which is close to the break line of board or on the
line of large holes of board.
l
Do not bend extremely the board, in mounting another
component. If necessary, use back-up pin (support pin) to
prevent from bending extremely.

Note that this product will be easily damaged by rapid heating,
rapid cooling or local heating.
Do not give heat shock over 100°C in the process of soldering.
We recommend to take preheating and gradual cooling
Soldering gun procedure
Note the follows, in case of using solder gun for replacement.
1) The tip temperature must be less than 280 for the period
within 3 seconds by using soldering gun under 30W
2) The soldering gun tip shall not touch this product directly.
Soldering volume
Note that excess of soldering volume will easily get crack the
body of this product.
