Crystals Procurement Notes

Verify the specific suffix ABKT against official manufacturer documentation to confirm the 20 pF load capacitance specification. Ensure that the ordering part number matches the required package style and electrical parameters exactly as defined in the current product datasheet before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 14.7456 MHz reference with 20 pF load capacitance is required for surface mount designs. Consider the ±30 ppm tolerance and ±50 ppm stability limits relative to the target application's timing accuracy requirements and operating temperature range constraints.

Crystals Part Context

This model belongs to the HCM49 series of crystals from Citizen Finedevice. The series offers various frequencies and load capacitances within the HC-49/US form factor. This specific variant provides a 20 pF load option distinct from other common values like 18 pF found in similar models.

Crystals Replacement Considerations

Substitutes must match the 14.7456 MHz frequency, 20 pF load capacitance, and HC-49/US SMD package. Verify equivalent tolerance and stability ratings to ensure circuit compatibility.
