• Mega Cap (Single or Two-Pile with Lead Frame) | TDK

TTI Expands inventory profile for TDK Mega Cap products and adds 100 piece cut-reel options (Part Number / 100).

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. The lead frame also absorbs other stresses such as vibration and temperature.

Compared to electrolytic capacitors, the TDK Mega Cap offers lower ESL, ESR, and improved frequency response. Since Mega Cap utilizes MLCC, they have no polarity. Mega Cap has higher reliability compared to electrolytics. The double stacked Mega Cap offers twice the capacitance in a single package. This reduces board real estate.
