Enhanced Safety Certified Surface-Mount MLCCs

Knowles Precision Devices' enhanced safety-certified MLCCs comply with international UL and IEC/EN specifications with certification by UL (inc. cUL) and TUV to ensure safety requirements are met. These capacitors have a high capacitance range of 4.7 pF to 56 nF, voltage ratings up to 305 V_RMS, and meet class Y2/X1, X1, and X2 requirements. The higher dielectric withstand voltages (DWV) of 4 kV_DC and 3 kV_RMS make these parts particularly suitable for electric vehicle (EV) applications, especially 800 V battery systems where an increased test voltage and safety margin is essential. The entire range is available with AEC-Q200 qualification, an essential requirement for these applications. The capacitors offer customers a unique combination of capability and safety certification and meet the demands of AEC-Q200 standards, modems, and ACDC power supplies where lightning strikes or other voltage transients represent a threat to electronic equipment.
