Resonators Procurement Notes

Verify the specific ordering suffix to confirm the packaging type and tolerance level. Ensure the selected variant matches the required load capacitance and frequency stability for the target application. Cross-reference the datasheet for any recent product change notifications or environmental compliance updates before finalizing procurement orders.

Resonators Selection Notes

Select this component when a stable 40 MHz reference is needed without external capacitors. Compare against other CSTLS_X series variants if different frequencies or tighter tolerances are required. Consider the through-hole form factor constraints and ensure the 2.50 mm pin pitch aligns with the available PCB footprint.

Resonators Part Context

This part belongs to the Murata CSTLS_X series of CERALOCK ceramic resonators. These devices combine piezoelectric elements with internal capacitors to provide precise timing solutions. The series is designed for cost-effective mass production while maintaining high reliability in consumer electronics and industrial applications requiring stable clock signals.

Resonators Replacement Considerations

Direct substitutes include other Murata parts within the CSTLS_X family sharing identical electrical parameters. Verify that alternative candidates maintain the same 40 MHz frequency, 5 pF internal capacitance, and ±0.2% tolerance specifications to ensure circuit compatibility.
