Crystals Procurement Notes

Verify the specific ESR value against the official manufacturer datasheet, as distributor listings may vary between 40 Ohms and other values. Confirm the package type matches the required PCB footprint. Ensure the load capacitance specification aligns with the target circuit design requirements before procurement.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency is required with a 20 pF load capacitance. The HC-49/US package is suitable for through-hole assembly processes. Consider the ESR specification to ensure compatibility with the driving circuit's oscillation conditions and stability requirements.

Crystals Part Context

This part belongs to YIC's line of quartz crystal resonators. These components are passive devices used to provide a stable reference frequency in electronic systems. The model number indicates the frequency, load capacitance, and package style, distinguishing it from surface mount or different frequency variants within the same product family.

Crystals Replacement Considerations

Substitute parts must match the 25 MHz frequency, 20 pF load capacitance, and HC-49/US package dimensions. Verify that the replacement component meets the same ESR specifications and operates in fundamental mode to ensure circuit compatibility.
