Procurement Notes

Verify the specific operating temperature range and stability requirements against application needs before procurement. Confirm that the HC-49/US package dimensions align with the target PCB layout constraints. Ensure the drive level specification matches the oscillator circuit design to prevent over-driving the crystal. Cross-reference the manufacturer part number with distributor listings to confirm current availability status.

Selection Notes

Select this component when a standard through-hole quartz crystal is required for 11.0592 MHz applications. Consider the 18 pF load capacitance requirement for circuit compatibility. Evaluate the ±30 ppm tolerance against system timing accuracy requirements. Assess the physical size constraints of the assembly process relative to the HC-49/US footprint.
