Procurement Notes
Verify the specific suffix against official documentation, as bulk packaging variants may differ from tape-and-reel configurations. Confirm current availability status directly with the manufacturer or authorized distributors, as supply conditions can change. Ensure the selected variant matches the required surface-mount footprint and thermal specifications for the target application environment.
Selection Notes
Select this component when a 4 MHz surface-mount crystal with HC-49/US dimensions is required. Verify that the 16 pF load capacitance aligns with the host circuit's oscillator requirements. Consider the -10°C to +60°C operating range to ensure suitability for the intended environmental conditions. Check ESR limits against the oscillator driver strength.
