CSTNE12M5G55A000R0

Resonators Overview

The Murata Electronics CSTNE12M5G55A000R0 is a CERALOCK ceramic resonator 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 and an impedance of 30 Ohms. Housed in a compact 3.2 mm x 1.3 mm x 0.7 mm SMD package, it supports an operating temperature range from -40°C to +125°C. This part is qualified under the AEC-Q200 standard for automotive reliability.

Resonators Feature Summary

• Integrated CERALOCK technology provides high frequency stability and low cost compared to crystal oscillators.
• Built-in capacitors simplify circuit design by eliminating external tuning components.
• Automotive-grade qualification ensures reliability in harsh environmental conditions.

Resonators Applications

• Microcontroller clock sources in automotive infotainment systems
• Timing references for automotive control units (ECUs)
• Clock generation for communication interfaces in vehicle electronics

Resonators Procurement Notes

Verify that the specific suffix 'A' confirms AEC-Q200 automotive qualification, as non-A variants may lack this certification. Ensure the ordering code matches the required 12.5 MHz frequency and 33 pF load capacitance. Confirm RoHS compliance status via the manufacturer's latest documentation before finalizing procurement specifications.

Resonators Selection Notes

Select this component when a stable, low-cost timing source is required for automotive applications. The 33 pF internal capacitance must match the microcontroller's specified load requirements. Consider the 30 Ohm impedance characteristic for driver compatibility. The wide temperature range suits under-hood or exterior electronic modules.

Resonators Part Context

This part belongs to the CSTNE series of CERALOCK ceramic resonators. It serves as a direct replacement for older discontinued models like the CSTCE12M5G55-R0. The series offers a balance between performance and size, utilizing a small 3-SMD footprint suitable for dense PCB layouts in modern electronic assemblies.

Resonators Replacement Considerations

The CSTCE12M5G55-R0 is officially listed as a discontinued substitute. Verify pinout compatibility and ensure the replacement maintains the same 12.5 MHz frequency and 33 pF load capacitance requirements for the target circuit.
