Resonators Procurement Notes

Verify the specific suffix GH5L against the manufacturer's current datasheet to ensure compatibility with required load capacitance and tolerance specifications. Confirm that the 39 pF internal capacitor aligns with the target oscillator circuit requirements. Check for any recent product change notifications regarding manufacturing location or material composition updates before finalizing procurement orders.

Resonators Selection Notes

Select this component when a 7.37 MHz reference is needed with tighter stability than standard variants. Ensure the host oscillator circuit can accommodate the 39 pF internal capacitance without additional external components. Compare against the CSTCR series if lower cost is prioritized over stability, noting differences in tolerance and temperature range specifications.

Resonators Part Context

This part belongs to the CERALOCK CSTNR_GH5L series, designed for general-purpose clock generation. It serves as a cost-effective alternative to quartz crystals while offering better stability than basic ceramic resonators. The series is optimized for mass production in consumer and industrial electronics where moderate precision is sufficient.

Resonators Replacement Considerations

Direct substitutes include the CSTCR7M37G53-R0, though it has different stability and capacitance characteristics. Verify pinout compatibility and electrical parameters before swapping. No other exact equivalent part numbers are publicly confirmed by the manufacturer for this specific model.
