NEW! ECK-THC Series Ceramic Capacitors
Molded Surface Mount Ceramic Y1 Capacitors
Safety Requirement Approved
Panasonic, a worldwide leader in Capacitor Products, now offers the NEW ECK-THC Series Surface Mount
Ceramic Sub-Class Y1-Rated Capacitors for power supply applications. This Series is for line-to-ground use
and has a voltage rating of 250 VAC. The NEW ECK-THC Series offers capacitance values of 100, 220, and
470pF and capacitance tolerances of +/-10 or +/-20%. Flexible style terminations afford a greater measure
of safety. ECK-THC Series Surface Mount Y1-Rated capacitors are a unique industry offering. Earlier
solutions were a Radial Leaded (Through-Hole) Capacitor or two (2) Y2 Surface Mount Capacitors in series.
