Crystals Procurement Notes

Verify the specific suffix A against the official CTS datasheet to confirm the 10pF load capacitance and ±10ppm tolerance parameters. Ensure the ordering part number matches the exact frequency specification of 24.5535 MHz. Cross-reference the package dimensions and RoHS compliance status with the manufacturer's latest documentation before finalizing procurement.

Crystals Selection Notes

Select this component when a compact SMD crystal requires tight frequency tolerance of ±10 ppm. The 10pF load capacitance suits circuits designed for lower capacitive loading compared to standard 20pF variants. Verify that the 60 Ohm ESR is compatible with the oscillator circuit's drive level requirements, typically 10 µW for this series.

Crystals Part Context

This part belongs to the CTS 403 Series of surface-mount crystals. It utilizes AT-cut quartz technology for stable performance across the specified industrial temperature range. The 4-SMD no-lead package facilitates automated assembly in high-volume manufacturing environments for consumer and industrial electronics.

Crystals Replacement Considerations

Direct substitutes include other CTS 403 series parts with matching 24.5535 MHz frequency, 10pF load capacitance, and ±10ppm tolerance. Verify package compatibility and ESR values when considering alternatives from other manufacturers.
