Resonators Procurement Notes

Verify the specific suffix codes against official Murata documentation to ensure correct tolerance and temperature ratings. Confirm that the required load capacitance matches the internal 15 pF specification to avoid oscillation failures. Check RoHS compliance status via the manufacturer's datasheet before finalizing procurement decisions.

Resonators Selection Notes

Select this component when design constraints require simplified oscillator circuits without external capacitors. Ensure the operating environment stays within the specified -20°C to +80°C range. Compare the 50 Ohm impedance against controller requirements to guarantee stable oscillation amplitude and waveform quality.

Resonators Part Context

This part belongs to the CSTCR_G series of small-cap chip type ceramic resonators. It utilizes Murata's CERALLOCK technology to integrate piezoelectric elements with embedded capacitors. This integration distinguishes it from standard discrete ceramic resonators that require external components for proper operation.

Resonators Replacement Considerations

Direct substitutes must match the 4 MHz frequency, 15 pF internal capacitance, and SMD package dimensions. Verify equivalent impedance characteristics and temperature stability ranges. Cross-reference with other Murata CERALOCK variants ensuring identical electrical parameters for seamless integration.
