CSTCR4M10G55-R0

Resonators Overview

The CSTCR4M10G55-R0 is a small-cap chip type ceramic resonator manufactured by Murata Electronics under the CERALOCK series. It operates at a nominal frequency of 4.1 MHz with a tolerance of ±0.5%. The component features an integrated load capacitance of 39 pF and utilizes SMD/SMT termination for surface mount applications. It is housed in a non-standard 3-SMD package measuring 4.5 mm in length, 2 mm in width, and 1.15 mm in height. The device supports an operating temperature range from -20°C to +80°C.

• Integrates built-in capacitors to simplify circuit design
• Offers high frequency stability with tight tolerance
• Compact surface-mount form factor for space-constrained layouts

Resonators Applications

• Microcontroller clock sources
• Communication module timing circuits
• Embedded system oscillators

Resonators Procurement Notes

Verify the specific suffix R0 against official Murata documentation to confirm reel packaging specifications. Ensure the target application circuit matches the 39 pF internal load capacitance requirement. Confirm RoHS compliance status through the manufacturer's latest datasheet before final procurement decisions.

Resonators Selection Notes

Select this component when a stable 4.1 MHz reference is required for surface-mount designs. Compare against other CERALOCK variants if different frequencies or load capacitances are needed. Validate thermal performance within the specified -20°C to +80°C range for the intended environment.

Resonators Part Context

This part belongs to the CSTCR_G series of ceramic resonators. It serves as a cost-effective alternative to quartz crystals in applications where moderate frequency accuracy suffices. The CERALOCK branding indicates Murata's proprietary technology for miniaturized resonant components.

Resonators Replacement Considerations

Consult Murata's official substitution guide for direct equivalents. Verify that any replacement maintains the 4.1 MHz frequency, 39 pF load capacitance, and compatible physical footprint.
