Crystals Procurement Notes

Verify the specific suffix 'IDR' against official CTS documentation to confirm tape-and-reel packaging and lead-free compliance. Ensure the target circuit design accommodates the 18 pF load capacitance and 100 Ohm ESR specifications. Confirm that the -40°C to +85°C temperature range meets the operational requirements of the final application environment before procurement.

Crystals Selection Notes

Select this component when a sub-miniature footprint of 2.0mm x 1.6mm is required for 25 MHz timing. It is appropriate for designs needing ±20 ppm initial tolerance and 18 pF load matching. Consider the hermetic ceramic construction for enhanced reliability compared to non-hermetic alternatives in harsh environments.

Crystals Part Context

This part belongs to the CTS 402 Series, which offers sub-miniature surface-mount crystals. The series provides fundamental mode operation across various frequencies, utilizing hermetic ceramic packages to maintain performance stability. The 402 series is engineered for commercial and industrial applications requiring compact size and reliable frequency control.

Crystals Replacement Considerations

Direct substitutes within the same series include parts with identical electrical parameters but different suffixes indicating packaging variations. Verify compatibility with existing PCB footprints and reflow profiles when considering alternative package options from the manufacturer.
