Description

X7R capacitors with a defined capacitance variation under applied dc voltage, across the full operating temperature range. Whilst the capacitance of C0G/NP0 chips does not vary with applied voltage, standard X7R capacitors exhibit capacitance fluctuation but with no specified limit. For applications where a limit is required, Knowles is able to offer either a “B” code dielectric (conforms to MIL “BX” dielectric and IECQ-CECC “2X1”) or “R” code dielectric (conforms to MIL “BZ” dielectric and IECQ-CECC “2C1”).
