Crystals Procurement Notes

Verify that the specific part number matches the required HC-49/US form factor and 20 pF load capacitance. Confirm that the ±30 ppm tolerance meets the timing accuracy requirements of the target application. Ensure the 1 mW maximum drive level is compatible with the host oscillator circuit to prevent frequency pulling or damage. Check datasheet specifications for operating temperature range compliance.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for 11.0592 MHz applications. The HC-49/US package offers a balance of performance and ease of assembly for through-hole designs. Consider the ±30 ppm tolerance against system timing constraints. Evaluate the 50 Ohm ESR against the oscillator circuit's loading requirements. This part is suitable for general-purpose digital logic timing where moderate stability suffices.
