Enhanced 250Vac & 305Vac Capacitors


Knowles' latest enhanced range of Safety Certified capacitors complies with international UL/cUL and IEC/EN 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 allows us to offer capacitance ranges that are among the highest in the market for selected case sizes. Applications include: modems and other telecoms equipment, AC-DC power supplies, power distribution switchgear, automotive applications, and where lightning strike or other voltage transients represent a threat to electronic equipment.
