Crystals Procurement Notes

Verify the specific suffix 'A35H' against the official CTS datasheet to confirm the exact load capacitance and ESR specifications. Ensure the selected variant matches the required PCB footprint dimensions of 5.00mm x 3.20mm. Confirm RoHS3 compliance status if restricted materials are prohibited in the target assembly process.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency is required with a 32 pF load capacitance. The 30 Ohm ESR value must align with the oscillator circuit's drive level requirements. Consider the -10°C to +60°C temperature range suitability for the intended operational environment before finalizing the design.
