Crystals Procurement Notes

Verify the specific suffix 'D' against the required datasheet revision, as it may indicate specific material or packaging variations compared to other series variants. Confirm that the 18pF load capacitance matches the target circuit design requirements. Ensure the 40 Ohm ESR value is within the acceptable limits of the host oscillator circuit to guarantee reliable startup and operation. Check for any specific handling instructions regarding moisture sensitivity level 1 compliance during storage and reflow soldering processes.

Crystals Selection Notes

Select this component when a 25 MHz fundamental mode crystal is required for space-constrained applications due to its compact 6.00mm x 3.50mm footprint. The 40 Ohm ESR and 18pF load capacitance must align with the specific oscillator circuit design to ensure proper frequency accuracy. Consider the ±30 ppm tolerance if higher precision is not critical. Verify compatibility with standard surface-mount reflow profiles and confirm that the operating temperature range meets the environmental conditions of the final application.

Crystals Part Context

This part belongs to the CTS 406 Series of surface-mount crystals, designed for general-purpose timing applications. The series offers various frequencies and package sizes, with the 406I35D variant specifically providing a balance of performance and size. It serves as a cost-effective solution for mass-produced electronics requiring reliable frequency generation without the complexity of active oscillators.

Crystals Replacement Considerations

Direct substitutes include parts from the same family with identical electrical parameters but different suffixes, such as 406I35E25M00000, which may differ in packaging or minor manufacturing details. Cross-brand replacements require careful verification of load capacitance, ESR, and frequency tolerance to ensure circuit compatibility.
