Procurement Notes

Verify the specific suffix designation against manufacturer documentation to confirm packaging configuration and compliance status. Ensure that the required load capacitance matches the target circuit design parameters before procurement. Confirm availability status directly with authorized distributors as supply conditions may vary. Cross-reference the part number with official IQD Frequency Products catalogs to validate current production status and any potential obsolescence notices prior to ordering.

Selection Notes

Select this component when a through-hole mounting solution is required for 20 MHz applications. The HC-49/U package offers robust mechanical stability compared to surface mount alternatives. Consider the ±50ppm stability specification relative to the system's timing accuracy requirements. Evaluate the operating temperature range limits against the intended environmental conditions. Ensure the 30pF load capacitance aligns with the oscillator circuit design specifications.

Part Context

This part belongs to the IQD Frequency Products quartz crystal lineup, which includes various fundamental and overtone modes.
