Make sure that you account for the impact of DC bias on the capacitors value. It can be significant.
For instance, here are the characteristics for a 1uF, 100V X7R ceramic in a 1206 package. You can see that at 40 Volts, the capacitance has dropped by 40%. If you're operating it at elevated temperature, you can loose another 10% to 15%.
