TDK Open Mode

TDK Open Mode is a type of MLCC in which the gap between the terminal electrode and the internal electrode on the opposing terminal electrode side (called L-Gap) is longer than that of regular products. By making the overlapping portion of the opposing internal electrodes shorter, it is ensured that the opposing electrodes do not overlap at places where cracks may occur. Due to this, the risk of short-circuit can be reduced even if cracks should occur.

Applications

Areas where board flex has occurred repeatedly, areas with high risk, or problematic areas
Applications in which high reliability is required and mechanical stress is high
Battery line circuits that are susceptible to bending stress of the board

Circuits over 20A
DC-DC converters, etc.
Parts where a safety design is particularly required, including power circuits. Decoupling, smoothing, surge countermeasures, ESD
