Crystals Procurement Notes

Verify the specific pinout configuration and mechanical dimensions against the official datasheet before integration to ensure compatibility with the target PCB footprint. Confirm that the operating environment remains within the specified temperature range to maintain the guaranteed frequency tolerance and aging rates over the component's operational lifetime.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for 40 MHz applications with an 8 pF load capacitance requirement. The 60 Ohm ESR value suits circuits designed for lower impedance matching compared to higher ESR alternatives. Ensure the driving circuitry limits power consumption to the specified 100 µW maximum drive level to prevent frequency drift or physical damage to the resonator.

Crystals Part Context

This part belongs to the C1E series of low-profile surface mount crystals from Aker Technology Corp. The series provides fundamental mode options across various frequencies, utilizing standardized SMD packages to facilitate automated assembly processes. The C1E designation indicates a specific form factor optimized for space-constrained electronic designs requiring reliable frequency control.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 8 pF load capacitance, and 60 Ohm ESR specifications. Verify that alternative components support the same 4-pin SMD no-lead package dimensions and fundamental mode operation to ensure electrical and mechanical interchangeability without redesigning the host circuit board.
