Crystals Procurement Notes

Verify the specific suffix codes against official Siward documentation to confirm exact electrical parameters and packaging configurations. Ensure that the requested part matches the required frequency tolerance and load capacitance specifications for the target circuit design. Cross-reference manufacturer datasheets to validate compliance with RoHS and other relevant environmental standards before finalizing procurement orders.

Crystals Selection Notes

Select this component based on the requirement for a 39 MHz frequency with ±8 ppm stability in a small form factor. Consider the 10 pF load capacitance requirement when designing the oscillator circuit to ensure proper frequency accuracy. Evaluate the 50 Ohm ESR against the oscillator circuit's drive level limitations to prevent over-driving the crystal. Confirm that the 2.0 x 1.6 mm package fits within the available PCB real estate constraints.

Crystals Part Context

This crystal belongs to Siward's SMD crystal lineup, characterized by small footprint options suitable for portable devices. The XTL501140 series typically offers fundamental mode operation for lower power consumption compared to overtone modes. It serves as a critical timing element in systems requiring reliable clock signals without the need for large through-hole components.

Crystals Replacement Considerations

Direct substitutes must match the 39 MHz frequency, 10 pF load capacitance, 50 Ohm ESR, and ±8 ppm tolerance. Verify package dimensions of 2.0 x 1.6 mm 4-SMD No Lead for mechanical compatibility. Check manufacturer datasheets for equivalent parts from other suppliers offering identical electrical characteristics and mounting profiles.
