Selection Guidance

When selecting this capacitor, verify the DC bias effect on capacitance, especially for higher voltage applications. The X7R dielectric provides moderate stability; for stricter tolerance requirements, consider C0G/NP0 alternatives. Ensure the 0402 footprint matches your PCB design and that the voltage rating exceeds your maximum circuit voltage. For detailed specifications, refer to the official datasheet.
