If you have noticed a difference in the KEMET C4BS series capacitor, where the new model has a tab-like line on the top while the older version does not, please see the clarification below from the Kemet:
The manufacturer confirmed that this difference is due to the use of two different suppliers for the capacitor boxes. This variation is purely cosmetic and does not impact the performance or functionality of the capacitors.
You can use the capacitor without any concerns.
