Crystals Procurement Notes

Verify the specific suffix 'G30' against official manufacturer documentation to confirm compliance with RoHS standards and lead-free requirements. Ensure the 30 Ohm ESR specification matches the target circuit design before procurement. Cross-reference the 4-SMD package dimensions with PCB layout constraints to guarantee proper footprint compatibility during assembly.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required with tight ±10 ppm tolerance. The 12 pF load capacitance must align with the oscillator circuit's capacitive requirements. Choose this model over higher ESR variants if the application demands lower power consumption and faster startup times within the specified frequency range.
