Crystals Procurement Notes

Verify the specific suffix CKT against official CTS documentation to confirm packaging type and compliance status. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity. Check current availability as components may be subject to discontinuation or supply constraints. Confirm that the load capacitance matches the target circuit design requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 27.12 MHz reference with ±10 ppm stability is required for space-constrained designs. Ensure the application circuit supports an 8 pF load capacitance to maintain frequency accuracy. Verify that the operating temperature range of -20°C to +70°C aligns with the environmental conditions. Consider the 4-SMD package dimensions for PCB layout compatibility and soldering process requirements.
