Crystals Procurement Notes

Verify the exact datasheet from Aker Technology Corp to confirm current manufacturing status and detailed electrical limits. Ensure that the 4-SMD footprint matches the target PCB layout dimensions precisely. Confirm RoHS compliance requirements align with regional regulatory standards before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency is required with specific 12 pF load capacitance matching. Consider the 70 Ohm ESR value for oscillator drive level calculations to ensure stable operation without overdriving the crystal. Evaluate the ±15 ppm tolerance against system jitter requirements.

Crystals Part Context

This part belongs to the C2E series of surface-mount crystals from Aker Technology Corp. The series offers various frequency options within a standardized small outline package. The C2E designation indicates a specific package style and mounting configuration distinct from other Aker product lines like C3E or C7S.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 12 pF load capacitance, and 4-SMD no-lead package. Verify equivalent ESR values and tolerance grades to maintain circuit performance. Cross-reference pinout compatibility if alternative manufacturers offer similar form factors.
