KEMET KPS L Series SnPb Termination X7R SMD MLCCs
KEMET KPS L Series SnPb Termination X7R SMD MLCCs utilize a proprietary lead-frame technology to vertically stack one or two MLCCs into a single compact SMD package. The attached lead frame mechanically isolates the capacitors from the printed circuit board. This offers advanced mechanical and thermal stress performance. Audible, microphonic noise that may occur when a bias voltage is applied is addressed through isolation. A two-chip stack offers up to twice the capacitance in the same or smaller design footprint when compared to traditional surface-mount MLCC devices. Applications for KEMET KPS L Series SnPb Termination X7R SMD MLCCs include switch-mode power supplies, high-voltage coupling and DC blocking, lighting ballasts, voltage multiplier circuits, smoothing circuits, and much more.
