Multilayer Ceramic Chip Capacitors

Product Overview
C Series: Open Mode Capacitor

The C Series Open Mode MLCCs are used for crack mitigation purposes in applications exhibiting high mechanical stress.

View Product List

TDK Open Mode Series MLCC is designed with a wider gap between the terminal and the internal electrodes to help reduce the risk of short circuit in the event of capacitor cracking due to mechanical stress such as board bending. By utilizing a unique internal electrode design, the counter electrode avoids the board flex’s typical crack path.

Composed of only ceramics and metals, Open Mode Series provides extremely dependable performance, exhibiting virtually no degradation, even when subjected to temperature extremes (+125deg C and +150deg C temperature ranges are available). TDK’s Open Mode MLCCs are available in case sizes 0805, 1206, 1210, 1812, and 2220.
