M Series 270 pF X7R MLCC at 16 V
The EMK063B7271KP-F: 16 VDC rating gives comfortable voltage margin for typical 5 V and 12 V SMPS rails; for a 0201 ceramic, the recommended derating ceiling sits at roughly 50% of rated voltage under continuous DC bias, so the 16 V part is appropriately sized for these applications without needing the next voltage step. 270 pF at 16 V serves as a high-frequency bypass or coupling element in the switching node — at these values the ESL of the 0201 package is still low enough for effective decoupling above 100 MHz in compact power stages where board area is constrained.
