Multilayer Ceramic Capacitors
Approval Sheet
1. DESCRIPTION
WTC’s SAFETY CERTIFIED CAPACITORS are designed for surge or lightning immunity in modem facsimile and
other equipment. The capacitors of series S3 are class X2 compliant respectively.
The green type capacitors in S2 and S3 series are manufactured by using environmentally friendly materials without
lead or cadmium.
The terminations are composed of plated nickel and pure tin to feature the superior leaching resistance during
soldering.
