CSTNE12M5G55Z000R0

Resonators Overview

The CSTNE12M5G55Z000R0 is a ceramic resonator from Murata Electronics' CERALOCK series, designed for surface mount applications. It operates at a nominal frequency of 12.5 MHz with an initial tolerance of ±0.50% and frequency stability of ±0.2%. The component features a built-in load capacitance of 33 pF, eliminating the need for external capacitors in many circuits. It is housed in a compact 3.2 mm x 1.3 mm x 0.7 mm SMD package. The device supports a wide operating temperature range from -40°C to +125°C, ensuring reliability in demanding environments.

Resonators Feature Summary

• Integrated 33 pF load capacitance simplifies circuit design by removing the requirement for external capacitors.
• High frequency stability of ±0.2% ensures precise timing performance across the specified temperature range.
• Extended operational temperature capability up to +125°C suitable for industrial and automotive applications.

Resonators Applications

• Microcontroller clock sources
• Communication interface timing
• Industrial control systems

Resonators Procurement Notes

Verify the specific suffix 'Z000' against official Murata documentation to confirm the exact tolerance and temperature grade, as variations exist within the CSTNE series. Ensure compatibility with standard reflow soldering profiles for 3-SMD components. Cross-reference RoHS and REACH compliance status directly with the manufacturer's current declarations prior to final procurement decisions.

Resonators Selection Notes

Select this component when a cost-effective alternative to quartz crystals is required with moderate precision needs. The integrated capacitor reduces board space and assembly complexity compared to discrete crystal solutions. Consider the ±0.50% initial tolerance for applications where strict frequency accuracy is not critical. Verify that the 12.5 MHz frequency aligns with the target system's clock requirements.

Resonators Part Context

This part belongs to the CERALOCK CSTNE series, which are ceramic resonators known for their compact size and low cost. It serves as a successor or alternative to older series like CSTCE, offering improved temperature characteristics. The CSTNE line is widely used in consumer electronics and industrial equipment where small form factor and reliable timing are essential.

Resonators Replacement Considerations

The discontinued CSTCE12M5G55-R0 is a confirmed substitute. Both parts share identical electrical specifications including 12.5 MHz frequency, 33 pF capacitance, and ±0.5% tolerance. The primary difference lies in the operating temperature range; the CSTNE variant supports up to +125°C, whereas the CSTCE is limited to +80°C. Pinout and footprint dimensions remain compatible for direct replacement.
