• Consumer electronics control boards

Resonators Procurement Notes

Verify the specific suffix B0 against the official Murata datasheet to confirm pinout and mechanical tolerances. Ensure the selected variant matches the required 47 pF load capacitance for the target application. Cross-reference the through-hole package dimensions with the PCB footprint library to prevent assembly errors. Confirm compliance with RoHS directives if required by the end product specifications.

Resonators Selection Notes

Select this component when a low-cost, reliable clock source is needed for through-hole designs. It is appropriate for applications where moderate frequency stability suffices and space constraints allow for larger packages than surface-mount alternatives. Consider the 4.91 MHz frequency against available microcontroller input requirements. Evaluate the thermal range against the operational environment limits.

Resonators Part Context

This part belongs to the CSTLS_G series of ceramic resonators. It serves as a middle-ground solution between inexpensive ceramic filters and high-precision quartz crystals.
