Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required load capacitance and ESR values. Confirm that the package dimensions align with the PCB footprint design rules. Check for any recent revisions in the RoHS compliance status or material composition declarations prior to final procurement approval.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required for UWB or wireless applications. Ensure the circuit design accommodates the specified 8 pF load capacitance to maintain frequency accuracy. Consider the ±10 ppm tolerance relative to system timing requirements and verify that the operating temperature range meets the environmental conditions of the end application.

Crystals Part Context

This part belongs to Aker Technology's C16 series of surface-mount crystals, specifically engineered for high-frequency wireless applications. The series offers various frequency options within a standardized 1612 package size, facilitating consistent board layout strategies across different product lines while maintaining reliable performance in consumer electronics and IoT devices.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 8 pF load capacitance, and 1612 SMD package dimensions. Verify equivalent ESR and aging specifications to ensure circuit stability. Cross-reference with other manufacturers offering UWB-specific crystals in the same form factor.
