Why Your 10 µF Capacitor Is Not 10 µF: Case Size, DC Bias & Effective Capacitance
Three Samsung capacitors — same 10 µF, same X5R, same 25 V rating. At 12.5 V of DC bias the 1206 delivers 2.4× the capacitance of the 0603. Samsung’s own published curves, the physics behind them, and why the TrueVolt LN-7A2033 and PureRail C33 Nano use a 1206.
