CKG Series Multilayer Ceramic Chip Capacitors

TDK's single and double-stacked configuration MLCCs

Image of TDK's CKG Series Multilayer Ceramic Chip CapacitorsTDK's mega caps CKG series MLCCs have lead frames attached. They are available in single- and double-stacked configurations.

TDK's mega caps utilize an alloy 42-lead frame connected to the ends of MLCCs in single- or double-stacked (piled) configuration. The lead frame absorbs external stresses which allows for a more robust performance. Effectively, the lead frame allows external stresses beyond the typical allowable range for a traditional MLCC. Mega caps are excellent choices for high board flex applications as well as physically large boards that are highly susceptible to flexure. Other flex solutions are designed to resist short circuits but still cause the capacitor to fail intermittently or completely. Mega caps have a greater degree of flexure resistance without capacitor failure.

The lead frame also absorbs other stresses such as vibration and temperature. Compared to electrolytic capacitors, Mega Caps offer lower ESL and ESR and have an improved frequency response. Since mega caps utilize MLCCs, they have no polarity. Series CKG mega caps have higher reliability compared to electrolytic capacitors.
