Crystals Procurement Notes

Verify the specific frequency tolerance requirement against the datasheet specification of ±10 ppm to ensure compatibility with system timing constraints. Confirm that the PCB layout supports the 1612 SMD package dimensions and no-lead termination style. Ensure the load circuit matches the 12 pF design parameter to maintain accurate frequency performance. Check RoHS compliance status if environmental regulations apply to the final product assembly.

Crystals Selection Notes

Select this component when a 25 MHz reference is required with tight ±10 ppm stability limits. The 1612 package offers a balance between size and manufacturability for surface-mount processes. Consider the 80 Ohm ESR value when designing the oscillator circuit to ensure reliable startup. Compare against other Aker C1E series variants if different frequencies or load capacitances are needed for alternative system designs.

Crystals Part Context

This part belongs to the Aker C1E series of MHz crystals, which are widely used in consumer and industrial electronics. The series provides various frequency options in standardized surface-mount packages. The C1E-25.000 variant specifically targets common 25 MHz clocking needs found in USB interfaces, Ethernet controllers, and general-purpose digital logic timing applications.

Crystals Replacement Considerations

Direct substitutes must match the 25 MHz frequency, ±10 ppm tolerance, 12 pF load capacitance, and 1612 SMD package. Verify ESR compatibility around 80 Ohms. Cross-reference with other manufacturers offering identical electrical parameters and mechanical dimensions to ensure pinout and footprint equivalence.
