CSTNE12M2GH5L000R0

Resonators Overview

The CSTNE12M2GH5L000R0 is a surface-mount ceramic resonator manufactured by Murata Electronics, part of the CERALOCK® CSTNE series. It operates at a nominal frequency of 12.288 MHz with an initial frequency tolerance of ±0.07% and stability of ±0.11%. The component features a built-in load capacitance of 33 pF, eliminating the need for external capacitors in typical oscillator circuits. It is housed in a compact 3-SMD non-standard package measuring 3.20 mm in length, 1.30 mm in width, and 0.80 mm in height. The device supports a wide operating temperature range from -40°C to +85°C and complies with RoHS3 standards.

Resonators Feature Summary

• Integrates internal load capacitance to simplify circuit design and reduce component count
• Provides high frequency stability suitable for precise timing applications
• Offers a compact surface-mount footprint for space-constrained PCB layouts

Resonators Applications

• Microcontroller clock sources requiring stable timing references
• Communication modules utilizing standard baud rates derived from 12.288 MHz
• Consumer electronics with limited board space for oscillators
• Industrial control systems operating within extended temperature ranges

Resonators Procurement Notes

Verify that the specific suffix GH5L corresponds to the required 33 pF internal capacitance and ±0.07% tolerance, as variations exist within the CSTNE family. Confirm that the application circuit does not require additional external loading capacitors, as the internal value is fixed. Ensure the PCB footprint matches the 3.2mm x 1.3mm SMD dimensions and that soldering profiles comply with the thermal specifications for ceramic resonators. Check for RoHS3 compliance requirements if applicable to the final assembly.

Resonators Selection Notes

Select this component when a cost-effective alternative to quartz crystals is needed without sacrificing significant accuracy. The 12.288 MHz frequency is ideal for generating standard UART baud rates (e.g., 115200 bps) directly. Consider the ±0.11% stability against environmental temperature changes; if tighter stability is required across the full -40°C to +85°C range, a quartz crystal may be more appropriate. The built-in capacitor simplifies layout but limits flexibility in adjusting load capacitance for fine-tuning oscillator circuits.

Resonators Part Context

This part belongs to Murata's CERALOCK® CSTNE series, designed as a drop-in replacement for discrete crystal oscillator circuits. The series emphasizes miniaturization and ease of use by integrating necessary passive components. The CSTNE12M2GH5L000R0 specifically targets applications where moderate frequency accuracy is sufficient, offering a balance between performance and manufacturing simplicity compared to higher-precision crystal units.

Resonators Replacement Considerations

Direct substitutes must match the 12.288 MHz frequency, 33 pF internal capacitance, and 3.2x1.3mm package. Verify equivalent stability ratings (±0.11%) and temperature range (-40°C to +85°C). Cross-reference with other manufacturers' ceramic resonators using similar pinouts and electrical characteristics to ensure functional compatibility in existing designs.
