Resonators Procurement Notes

Verify the specific suffix codes against the official Murata datasheet to ensure correct frequency, tolerance, and package dimensions. Confirm that the required load capacitance matches the system design requirements, as this model includes internal capacitors. Check RoHS compliance status and REACH SVHC declarations prior to final procurement approval.

Resonators Selection Notes

Select this component when a cost-effective alternative to quartz crystals is needed without sacrificing significant accuracy. The integrated capacitor reduces board space and assembly complexity. Ensure the application environment stays within the specified -40°C to +85°C temperature range for optimal performance.

Resonators Part Context

This part belongs to the CSTNE_G series of CERALOCK ceramic resonators. It serves as a direct replacement for older discontinued series like CSTCE in many standard designs. The G-series designation indicates specific electrical parameters and package variations within the broader CERALOCK product line.
