Crystals Procurement Notes

Verify the specific suffix 'J' indicates tape and reel packaging when ordering. Confirm that the required frequency tolerance of ±10 ppm aligns with system timing requirements. Ensure the operating temperature range of -20°C to +70°C meets environmental constraints. Cross-reference the 4-SMD footprint against PCB layout specifications to guarantee mechanical compatibility during assembly.

Crystals Selection Notes

Select this component when a fundamental frequency crystal near 30 MHz is required with tight stability constraints. The 9 pF load capacitance must match the oscillator circuit design. Consider the 80 Ohm ESR limit for drive level sensitivity. The RoHS-compliant construction supports environmentally regulated manufacturing processes. Evaluate thermal performance against the specified industrial temperature range.
