Crystals Procurement Notes

Verify the specific package variant against official datasheets, as naming conventions may vary between through-hole and surface-mount versions. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation prior to procurement to ensure regulatory adherence for your specific application requirements.

Crystals Selection Notes

Select this component when a 13.56 MHz frequency is required for surface-mounted designs. Ensure the circuit design accommodates the 20pF load capacitance and 50 Ohm ESR limits. Validate that the ±30 ppm tolerance meets the system's frequency stability requirements under expected operating temperature conditions.

Crystals Part Context

This part belongs to YIC's line of quartz crystal resonators, specifically utilizing the HC-49/US mechanical outline. The suffix indicates surface mount compatibility, distinguishing it from traditional through-hole variants while maintaining similar electrical characteristics for legacy footprint replacements.

Crystals Replacement Considerations

Direct substitutes must match the 13.56 MHz frequency, 20pF load capacitance, and surface mount HC-49/US package. Verify ESR and tolerance specifications against original design constraints before substitution.
