Procurement Notes

Verify the specific suffix requirements against the manufacturer's latest documentation to ensure compatibility with your circuit design. Confirm that the HC-49/US package dimensions align with your PCB layout constraints. Check for any recent product change notices regarding material composition or manufacturing location updates. Ensure the selected variant meets the required operating temperature range for your specific application environment.

Selection Notes

Select this component when a standard through-hole crystal is required for 14.7456 MHz applications. The 30 pF load capacitance must match the oscillator circuit design specifications. Consider the 40 Ohm ESR value for drive level calculations to prevent overdriving the crystal. Verify that the ±30 ppm tolerance meets the system timing accuracy requirements.
