Crystals Procurement Notes

Verify the specific ordering suffix to ensure the correct frequency and packaging configuration matches the design requirements. Confirm that the 4-SMD no-lead package aligns with the target PCB layout and soldering process capabilities. Cross-reference the manufacturer's datasheet for detailed reflow soldering profiles and storage conditions to maintain component integrity during assembly.

Crystals Selection Notes

Select this component when a 40 MHz reference signal with ±8 ppm stability is required in a minimal footprint. Ensure the application circuit supports a 10 pF load capacitance to achieve the specified frequency accuracy. Evaluate the 50 Ohm ESR against the oscillator circuit's drive level constraints to prevent overdriving the crystal element.

Crystals Part Context

This part belongs to the Siward XTL50 series of surface-mount quartz crystals. The series offers various frequencies within the 37.4 to 80 MHz range, packaged in small form factors such as 1.0x0.8mm and 2.0x1.6mm. These components are engineered for high-volume consumer and industrial electronics where size and performance consistency are critical.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz crystals with identical 2.0x1.6mm SMD packages and 10pF load capacitance. Verify that alternative parts meet the same ±8 ppm tolerance and 50 Ohm ESR specifications to ensure circuit compatibility without redesign.
