Resonators Procurement Notes

Verify the specific ordering suffix against official Murata documentation to confirm pin configuration and tolerance levels. Ensure the selected variant matches the required operating temperature range and package dimensions for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and compliance status before finalizing procurement plans.

Resonators Selection Notes

Select this component when a cost-effective, stable clock source is required for microcontrollers or logic circuits. The integrated capacitor eliminates external components, reducing board space. Choose this model over discrete crystals if moderate frequency stability suffices and lower BOM complexity is prioritized. Verify that the 30-ohm impedance aligns with the driving circuit requirements.

Resonators Part Context

This resonator belongs to the CERALOCK CSTLS family, characterized by built-in capacitors and through-hole construction. It serves as an alternative to standard quartz crystals in applications where high precision is not critical. The series offers a balance between performance and manufacturing simplicity, targeting consumer electronics and industrial control systems requiring reliable timing signals.

Resonators Replacement Considerations

Direct substitutes include other Murata CSTLS variants with matching frequencies and tolerances. Verify compatibility with existing footprints and electrical parameters when considering cross-brand alternatives.
