• Provides high frequency stability suitable for precise clock generation applications.
• Offers a compact surface-mount footprint for space-constrained PCB layouts.

Resonators Applications

• Microcontroller clock sources
• Communication interface timing
• Embedded system oscillators

Resonators Procurement Notes

Verify the specific suffix codes against official Murata documentation to ensure correct tolerance and packaging specifications. Confirm that the intended application environment remains within the specified -40°C to +125°C operational temperature range. Check for RoHS compliance status relevant to the target market regulations before finalizing procurement orders.

Resonators Selection Notes

Select this component when a stable 12 MHz reference is required with minimal external circuitry. The integrated 33 pF capacitor eliminates the need for discrete loading capacitors. Ensure the PCB footprint matches the 3.2 mm x 1.3 mm dimensions. Consider the ±0.2% initial tolerance if tight frequency accuracy is critical for the system synchronization requirements.

Resonators Part Context

This part belongs to the CERALOCK CSTNE series, designed as a drop-in replacement for traditional crystal oscillator circuits. It utilizes Murata's proprietary ceramic technology to achieve reliable performance. The series is widely used in consumer electronics and industrial control systems where cost-effective timing solutions are prioritized over ultra-high precision.

Resonators Replacement Considerations

The discontinued CSTCE12M0G55A-R0 is a direct functional equivalent. Verify pin compatibility and mounting dimensions before substitution. Other CSTNE variants with different frequencies or tolerances may require circuit adjustments.
