Crystals Procurement Notes

Verify the complete part number including the suffix 'DR' to ensure correct tape-and-reel packaging configuration. Confirm that the 18pF load capacitance matches the circuit design requirements. Check datasheet specifications for ESR limits and frequency drift over the specified industrial temperature range before finalizing procurement.

Crystals Selection Notes

Select this component when a 25 MHz fundamental resonance is required in a compact SMD form factor. Ensure the application circuit provides the specified 18pF load capacitance to maintain ±10 ppm accuracy. Consider the 100 Ohm ESR value for oscillator drive level constraints and verify compatibility with the target PCB land pattern dimensions.

Crystals Part Context

This crystal belongs to the 402 Series from CTS-Frequency Controls, designed for general-purpose timing applications. It serves as a passive frequency-determining element in electronic circuits, replacing older through-hole packages with a smaller surface-mount alternative suitable for high-volume manufacturing environments.
