Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Ensure the operating temperature range aligns with your environmental conditions. Cross-reference the datasheet for absolute maximum ratings to prevent component damage during integration.

Oscillators Selection Notes

Select this component when a precise 41.142 MHz reference is required in space-constrained designs. The 1.8V supply requirement makes it suitable for modern low-power digital systems. Consider the LVCMOS output compatibility with your target logic family. The small 2.0x1.6mm form factor allows for high-density board layouts where larger oscillators cannot fit.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and supply voltages. The 'PD' suffix typically indicates the inclusion of a power-down pin or standby functionality. This specific model provides a fixed frequency solution for applications requiring stable timing without the complexity of programmable clocks.

Oscillators Replacement Considerations

Direct substitutes must match the 41.142 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility if replacing with different manufacturers. Check if the alternative part supports the same standby functionality. Ensure thermal and electrical characteristics are equivalent to maintain system reliability.
