Resonators Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's official datasheet specifications against the physical markings on the device. Confirm that the received parts match the exact model designation and package dimensions. Ensure compliance with relevant environmental directives such as RoHS and REACH requirements before integration into final assemblies.

Resonators Selection Notes

Select this component when a precise 4 MHz clock source is required for microcontroller or logic circuit operation. Consider the specific load capacitance and temperature range requirements of the target application. Evaluate the trade-off between cost and performance compared to crystal oscillators, noting that ceramic resonators offer lower precision but simplified circuit designs.
