Crystals Procurement Notes

Verify the specific suffix 'HV' against official datasheets to confirm material composition and reliability specifications. Ensure compatibility with the target circuit's load capacitance requirements, as the component is specified for 8 pF. Confirm that the 60 Ohm ESR aligns with the oscillator circuit design to guarantee proper startup and stability during implementation.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency is required within a compact 3.2 x 2.5 mm SMD package. It is suitable for designs where a ±30 ppm tolerance and 8 pF load capacitance are acceptable. Consider the 60 Ohm ESR value when designing the oscillator circuit to ensure reliable performance across the intended operating conditions.
