Description

Our latest enhanced range of AEC-Q200 qualified 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.

Advantages over other safety certified MLCC ranges include:

• Class Y2: Rated voltages from 250Vac - 500Vac 
• Class X1: Wide range including 305V, 310V, 440V, 520V and 660Vac
• Class X2: Standardized ratings of 250Vac and 305Vac 
• All ranges have a safety certified dc voltage rating 
• All ranges are certified as humidity robustness grade IIIB (unique in the industry)

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.
