Surface Mount Multilayer Varistor
SC0402ML - SC0603ML 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.

Pad Layouts & Precaution for handling of substrate
Solder cream in reflow soldering
Refer to the recommendable land pattern as printing
mask pattern for solder cream.
(1) Print solder in a thickness of 150 to 200μm
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.
l Do not break the board by hand. We recommend to use
