Overview

MLCC Safety Certified MLCC Capacitors Safety Certified capacitors Knowles Safety Certified capacitors comply with international UL and TÜV specifications to offer designers the option of using a surface mount ceramic multilayer capacitor to replace leaded film types.
Offering the benefits of simple pick-and-place assembly, reduced board space required and lower profile, they are also available in a FlexiCap™ version to reduce the risk of mechanical cracking.
Knowles high voltage capacitor expertise means the range offers among the highest range available of capacitance values in certain case sizes.
Applications include: modems, AC-DC power supplies and where lightning strike or other voltage transients represent a threat to electronic equipment.
