C1808W154KCRACTU

Product Summary

The C1808W154KCRACTU KEMET ArcShield high voltage surface mount MLCC in X7R Dielectric is designed for use in high voltage applications susceptible to surface arcing (arc-over discharge). The C1808W154KCRACTU is available in automotive grade, which undergo stricter testing protocol and inspection criteria. Whether under-hood or incabin, the C1808W154KCRACTU is designed for mission and safety-critical automotive circuits or applications requiring proven, reliable performance in harsh environments. Automotive grade devices meet the demanding Automotive Electronics Council AEC–Q200 qualification requirements. Typical applications of C1808W154KCRACTU include switch mode power supplies (input filters, resonators, tank circuits, snubber circuits, output filters), high voltage coupling and DC blocking, lighting ballasts, voltage multiplier circuits, DC/DC converters and coupling capacitors.
