Selection Notes

When selecting this capacitor, verify the DC bias characteristics and derating requirements for your specific application. The X7R dielectric provides stable capacitance over a wide temperature range, but capacitance may vary with applied DC voltage. For high-frequency or high-Q applications, consider C0G/NP0 alternatives. Always confirm the exact specifications from the manufacturer's datasheet before design-in.
