Crystals Procurement Notes

Verify the specific suffix designation when ordering, as variants such as ATS036SM-1E may differ in packaging or environmental compliance status compared to the base model. Confirm that the required load capacitance matches the target circuit design to ensure accurate frequency operation. Check manufacturer datasheets for updated RoHS and REACH compliance declarations prior to final procurement decisions.

Crystals Selection Notes

Select this component when a standard 3.579545 MHz reference is required for surface-mount applications. Ensure the PCB layout accommodates the HC-49/US-SM footprint dimensions. Consider the ±30 ppm tolerance sufficient for general timing needs; tighter tolerances may require alternative series. Verify that the 150 Ohm ESR aligns with the oscillator circuit requirements.

Crystals Part Context

This part belongs to the ATS-SM series of surface-mount crystals from CTS-Frequency Controls. It serves as a direct surface-mount alternative to traditional through-hole HC-49/US packages, offering similar electrical characteristics in a compact form factor suitable for modern high-density PCB designs.
