1. DESCRIPTION
WTC’s SAFETY CERTIFIED CAPACITORS are designed for surge or lightning immunity in modem facsimile and
other equipments. The capacitors of series S2 are class X1/Y2 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.
