Crystals Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm load capacitance and tolerance specifications. Ensure the ordering part number matches the required frequency stability and package type for your design. Cross-reference the revision history for any updates to material composition or testing standards before finalizing procurement.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required in a compact SMD form factor. Consider the 10 pF load capacitance requirement for oscillator circuit design. Evaluate the ±7 ppm tolerance against system jitter requirements. Confirm that the 3.2 x 2.5 mm outline fits within the available PCB real estate constraints.

Crystals Part Context

This crystal belongs to Siward's standard surface-mount series, characterized by small footprints and lead-free terminations. It serves as a primary timekeeping element in digital electronics, replacing through-hole variants where board space is limited. The model designation indicates specific electrical parameters distinct from other frequencies in the same package family.

Crystals Replacement Considerations

Substitute parts must match the 40 MHz frequency, 10 pF load capacitance, and 4-SMD no-lead package. Verify equivalent frequency stability and temperature range compatibility. Check pinout and mechanical dimensions for direct replacement feasibility without layout modifications.
