Crystals Procurement Notes

Verify the specific load capacitance requirement of your oscillator circuit matches the 8pF specification to ensure accurate frequency performance. Confirm that the PCB footprint aligns with the SMD2520-4P package dimensions. Check for any specific handling requirements related to the seam seal technology during assembly. Ensure the operating temperature range meets your application's environmental conditions before finalizing the procurement order.

Crystals Selection Notes

Select this component when a 37.4 MHz frequency is required with moderate stability needs. The 70 Ohm ESR value should be compatible with the driving circuit's impedance characteristics. Consider the 8pF load capacitance compatibility with the host device's internal or external capacitors. The SMD2520-4P form factor offers a balance between size and electrical performance for space-constrained designs.

Crystals Part Context

This part belongs to the C2E series of surface-mount crystals from Aker Technology. The series typically includes various frequencies and package sizes, such as the C2E-38.400-10-1520-R and C2E-20.000-8-1010-R. These units share common design principles like seam sealing and RoHS compliance, differing primarily in frequency, load capacitance, and physical dimensions.

Crystals Replacement Considerations

Direct substitutes may include other 37.4 MHz crystals with similar ESR and load capacitance values. Verify package compatibility with existing PCB layouts. Cross-reference with Aker's other C2E variants if frequency adjustments are permissible.
