Crystals Procurement Notes

Verify the specific suffix 'BBK' against official datasheets to confirm the 20pF load capacitance specification, as variations exist within the 7B series. Confirm RoHS3 compliance status directly with the manufacturer or authorized distributors prior to procurement. Ensure the selected variant matches the required -40°C to +85°C temperature rating for the intended application environment.

Crystals Selection Notes

Select this component when a standard fundamental mode crystal is required for 12.288 MHz applications. The 20pF load capacitance must match the oscillator circuit design. Consider the 4-SMD package size for PCB layout constraints. Verify that the ±30ppm stability meets system timing requirements compared to higher precision alternatives.
