Crystals Procurement Notes

Verify the manufacturer part number against official Hefei Jingweite documentation to ensure authenticity. Confirm that the 4-SMD no-lead package matches your PCB footprint requirements. Check the specific lot code and date code if traceability is required for your production line. Ensure the load capacitance specification aligns with your circuit design before ordering.

Crystals Selection Notes

Select this component when a precise 40 MHz reference is needed for surface-mounted designs. The ±10 ppm tolerance suits general digital applications requiring stable timing. Consider the 60 Ohm ESR value for oscillator circuit compatibility. The wide temperature range makes it suitable for industrial or automotive contexts where environmental stability is critical.

Crystals Part Context

This part belongs to the quartz crystal family produced by Hefei Jingweite Electronics, a specialist in frequency control components. The model designation indicates a 40 MHz unit with standard commercial/industrial specifications. It is designed for integration into modern electronics where space constraints favor leadless surface mount technologies over traditional through-hole packages.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 10 pF load capacitance, and 4-SMD no-lead package dimensions. Verify equivalent ESR and tolerance ratings from other manufacturers. Cross-reference pinout configurations if available, though SMD crystals are typically non-polarized.
