Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct tolerance and packaging specifications. Confirm that the radial SMD package variant matches the intended PCB layout requirements. Cross-reference the ESR and load capacitance values with the target oscillator circuit design to guarantee proper startup and stability conditions before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 32.768 kHz frequency is required for timekeeping functions. Ensure the circuit design accommodates the 7 pF load capacitance and 40 kOhm ESR characteristics. The 2x6 mm cylindrical form factor must fit within the available board space constraints. Verify compatibility with the host device's oscillator input impedance and drive level limitations to prevent frequency drift or component failure during operation.
