Procurement Notes

Verify the specific package variant and termination style against the official datasheet before procurement. Confirm that the ±30 ppm tolerance meets the system requirements. Ensure the operating temperature range covers the intended environmental conditions. Check for any recent part number revisions or obsolescence notices from the manufacturer.

Selection Notes

Select this component when a 10 MHz reference is required with moderate stability. The HC-49/US form factor suits designs needing robust mechanical mounting. Consider the ESR value for oscillator circuit compatibility. Evaluate the thermal performance if the application involves significant self-heating or extreme ambient temperatures.

Part Context

This part belongs to the HC-49/US family of quartz crystals, widely used in electronics for precise frequency control.
