Crystals Procurement Notes

Verify manufacturer part numbers against official Suntsu Electronics documentation to ensure authenticity. Confirm that the specific suffix matches the required frequency and tolerance specifications. Check RoHS compliance status if environmental regulations apply to your manufacturing process. Request updated datasheets directly from authorized distributors to validate current production status and packaging details before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 20 MHz reference signal is required with moderate stability requirements. Ensure the target circuit supports a 12 pF load capacitance to maintain accurate frequency performance. Verify that the operating environment remains within the specified -40°C to +85°C range. Consider the physical dimensions of the HC-49/US package during PCB layout planning to ensure adequate clearance and proper soldering alignment.

Crystals Part Context

This crystal belongs to Suntsu Electronics' standard SMD crystal lineup, designed for general-purpose timing applications. The model number indicates specific electrical characteristics including frequency, load capacitance, and tolerance. Similar variants exist with different frequencies or tolerances within the same product family, sharing identical physical packaging and basic operational principles for consistent board design practices.

Crystals Replacement Considerations

Direct substitutes must match the 20 MHz frequency, 12 pF load capacitance, and HC-49/US package dimensions. Verify equivalent ESR values to ensure circuit compatibility. Cross-reference pin configurations and mounting requirements to prevent mechanical interference. Consult manufacturer cross-reference guides for approved alternative part numbers with identical electrical specifications.
