Crystals Procurement Notes

Verify the exact part number against official manufacturer documentation to ensure compatibility with circuit requirements. Confirm that the HC-49/US package dimensions align with PCB layout constraints. Ensure the operating temperature range specified in the datasheet meets the environmental conditions of the intended application. Cross-reference the load capacitance and ESR values with the oscillator circuit design to guarantee proper startup and stability.

Crystals Selection Notes

Select this component when a 27 MHz fundamental mode crystal is required for standard oscillator designs. The HC-49/US package offers robust mechanical support for through-hole assembly. Consider the ±20 ppm tolerance if high precision is not critical. Verify that the 30 pF load capacitance matches the external capacitors used in the Pierce oscillator configuration. Evaluate the 30 Ohm ESR against the drive level limitations of the host circuitry.
