This is where MLCC capacitor derating becomes important. Using a capacitor below its maximum rated voltage can provide additional operating margin and may help improve reliability. However, choosing a much higher voltage rating is not always the best solution because it can increase component size or cost.
MLCC Capacitor Derating How Much Voltage Margin Do You Really Need
When buying an MLCC capacitor, you may see specifications such as ±1%, ±2%, ±5%, ±10%, or ±20% tolerance. But what do these numbers actually mean? Does a 100nF capacitor with ±10% tolerance always measure exactly 100nF? And when should you choose a tighter tolerance?

When an MLCC capacitor becomes too expensive, difficult to source, or has a long lead time, replacing it with another brand can be a practical solution. But an MLCC replacement is not as simple as finding another capacitor with the same capacitance and voltage. A small difference in electrical or physical characteristics can affect the performance of the final product
MLCC Capacitor Replacement What Should You Check Before Switching
For hardware design engineers developing audio equipment, power management systems, smartphone sub‑circuits, or notebook computers, encountering an unexpected high‑pitched buzzing or whining sound from a printed circuit board can be frustrating. Often traced back to passive components, this phenomenon is colloquially known as the "singing capacitor" effect.
