Crystals Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lot traceability upon receipt. Ensure storage conditions maintain moisture sensitivity levels as specified for surface-mount components. Cross-reference part numbers carefully to distinguish between similar IL3W series variants with differing load capacitances or tolerances.

Crystals Selection Notes

Select this component when a 32.768 kHz reference frequency is required for low-power digital systems. Consider the 9 pF load capacitance requirement against the total circuit capacitance to ensure accurate frequency operation. Evaluate the ±20 ppm tolerance against application requirements for timekeeping accuracy. Verify that the 1.6 x 1 x 0.6 mm package fits within the available board space constraints.
