5 Frequently Asked Questions about “The role of soft connection between capacitors”
Why is TDK a soft termination capacitor?
The resin layer absorbs stress accompanying expansion or shrinkage of the solder joints due to thermal shock or flex stress on the board and prevents cracking of the capacitor element. TDK's soft termination capacitors not only improve vibration resistance and withstand tumbling shock, but even more so prevent bending and thermal cycling.
Are MLCC capacitors a good choice for mass production?
