CKG SERIES | Mega Capacitor
TDK Mega Cap utilizes 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 allow 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 circuit but still cause the capacitor to fail intermittently
or completely but the Mega Cap has a greater degree of flexure resistance
without capacitor failure. Compared to electrolytic capacitors, Mega Cap offers
lower ESL, ESR, and improved frequency response and since Mega Cap is an
MLCC, they have no polarity. Other advantages include higher capacitance with
higher voltage rating due to stacking the capacitors in parallel configuration.
