Crystals Procurement Notes

Verify the specific manufacturer datasheet for detailed electrical characteristics and mechanical drawings before finalizing designs. Confirm that the 4 pF load capacitance aligns with the host oscillator circuit requirements to ensure accurate frequency performance. Check for any specific handling precautions related to the leadless SMD package during assembly processes.

Crystals Selection Notes

Select this component when a 25 MHz reference signal is required in space-constrained applications. Ensure the host circuit can accommodate the 4 pF load capacitance specification. Consider the ±30 ppm tolerance if higher precision is needed, as other variants may offer tighter tolerances. Verify that the operating temperature range meets the environmental conditions of the target application.

Crystals Part Context

This part belongs to the C1E series of surface-mount crystals from Aker Technology Corp. The series offers various frequencies and package sizes for different timing needs. The C1E-25.000-4-3030-R specifically addresses the common need for a 25 MHz clock in embedded systems. It is distinct from oscillators, which include internal circuitry, whereas this is a passive resonator requiring an external oscillator circuit.

Crystals Replacement Considerations

Direct substitutes must match the 25 MHz frequency, 4 pF load capacitance, and 4-SMD no-lead package dimensions. Verify equivalent frequency tolerance (±30 ppm) and series resistance limits. Cross-reference with other manufacturers offering similar SMD crystals, ensuring pin compatibility and thermal specifications are identical.
