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.
