Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure alignment with required electrical parameters such as ESR, load capacitance, and frequency tolerance. Confirm that the package dimensions and pin configuration match the target PCB footprint requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for the 12 MHz frequency band. Ensure the circuit design supports the specified 70 Ohm ESR and 18 pF load capacitance. Verify that the operational environment falls within the -40°C to +85°C temperature range defined by the A2 suffix.

Crystals Part Context

This part belongs to the CSM1 series of surface mount crystals from Cardinal Components Inc. The series offers various cut types and overtone options. This specific model represents a fundamental AT-cut variant designed for standard surface-mount applications requiring moderate stability.

Crystals Replacement Considerations

Direct substitutes must match the 12 MHz fundamental frequency, 18 pF load capacitance, 70 Ohm ESR, and SMD package type. Verify compatibility with the -40°C to +85°C operating range.
