Crystals Procurement Notes

Verify the specific suffix 'E' against the manufacturer's datasheet to confirm the exact load capacitance and ESR specifications, as these parameters define the electrical performance. Ensure the ordering quantity aligns with the standard tape and reel packaging requirements provided by CTS-Frequency Controls. Cross-reference the lead time with current supply chain conditions, as availability may vary. Confirm that the 4-SMD footprint matches the target PCB layout constraints before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency with 20 pF load capacitance is required for space-constrained designs. The 4-SMD package offers a compact footprint suitable for high-density boards. Consider the ±30 ppm tolerance for applications requiring moderate frequency accuracy. Evaluate the 50 Ohm ESR against the oscillator circuit's drive level limitations to ensure stable operation without overdriving the crystal element.
