CSTCW33M8X51-R0

Resonators Overview

The CSTCW33M8X51-R0 is a ceramic resonator from Murata Electronics' CERALOCK series, designed for surface-mount applications. It operates at a nominal frequency of 33.8 MHz with a tolerance of ±5%. The component features an integrated load capacitance of 27 pF and utilizes a three-terminal SMD package measuring 4.5 mm in length, 2.0 mm in width, and 1.15 mm in height. It supports a wide operating temperature range from -40°C to +125°C, ensuring stability in demanding electronic environments.

Resonators Feature Summary

• Integrates internal load capacitors to simplify circuit design and reduce external component count.
• Provides stable frequency generation using piezoelectric ceramic technology within a compact surface-mount footprint.
• Engineered for high reliability across extended industrial temperature ranges.

Resonators Applications

• Microcontroller clock sources
• Communication module timing circuits
• Consumer electronics control boards

Resonators Procurement Notes

Verify the specific suffix 'R0' corresponds to the reel packaging configuration required for automated assembly processes. Confirm that the 27 pF integrated capacitance aligns with the target oscillator circuit's input requirements. Ensure the 33.8 MHz frequency matches the system clock specifications precisely. Check RoHS compliance status against current regulatory standards for the intended market.

Resonators Selection Notes

Select this component when a cost-effective, space-saving alternative to crystal oscillators is needed for moderate precision applications. The integrated capacitor eliminates the need for external discrete components, reducing board area. Consider the ±5% tolerance limit; if tighter frequency accuracy is required, a quartz crystal or higher-precision resonator should be evaluated instead.

Resonators Part Context

This part belongs to the CSTCW series of CERALOCK ceramic resonators, which are characterized by their built-in load capacitance feature. The series is widely used in consumer and industrial electronics where size constraints and assembly efficiency are critical. The specific model denotes the 33.8 MHz frequency variant within this standardized product line.

Resonators Replacement Considerations

Direct substitutes include other Murata CERALOCK models with identical 33.8 MHz frequency and 27 pF capacitance, such as CSTCW33M8X51-B95, provided the package dimensions and mounting compatibility remain unchanged. Cross-reference with competitor ceramic resonators only if electrical parameters and physical footprint match exactly.
