Crystals Procurement Notes

Verify the specific suffix 'B' indicates the correct load capacitance and ESR variant for your circuit design. Confirm that the 4-SMD footprint matches your PCB layout constraints. Check current availability as lead times may vary. Ensure compliance with RoHS3 requirements for your target market regulations before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 12 MHz fundamental frequency is required with strict size limitations. The 13 pF load capacitance must match the oscillator circuit design to achieve the specified ±30 ppm accuracy. Consider the 60 Ohm ESR value for drive level sensitivity. The extended temperature range makes it suitable for applications exceeding standard commercial limits.

Crystals Part Context

This part belongs to the CTS 405 series of surface-mount crystals. The series offers various frequencies and package sizes. The 'I' designation typically indicates industrial temperature range performance. This specific model provides a balance of size, stability, and cost-effectiveness for general-purpose timing applications.

Crystals Replacement Considerations

Direct substitutes include other 12 MHz crystals with identical 13 pF load capacitance and similar ESR values. Verify mechanical compatibility with the 5.00mm x 3.20mm footprint. Electrical parameters such as frequency tolerance and stability should be equal or better than the original specification.
