CSTCR7M28G53-R0

Resonators Overview

The Murata CSTCR7M28G53-R0 is a CERALOCK ceramic resonator operating at 7.28 MHz with ±0.5% frequency tolerance and ±0.2% stability. Designed for surface mount applications, it features a three-pin configuration in a 4.5mm x 2mm x 1.6mm package. The component supports a 15 pF load capacitance and operates within a temperature range of -40°C to +80°C.

Resonators Feature Summary

• Utilizes shear oscillation mode for stable frequency generation
• Small-cap chip type construction for compact circuit integration
• Three-terminal design simplifies mounting on printed circuit boards

Resonators Applications

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

Resonators Procurement Notes

Verify the specific part number against official Murata documentation to ensure compatibility with required frequency and load capacitance specifications. Confirm that the surface mount package dimensions align with the target PCB footprint. Check for RoHS and REACH compliance requirements relevant to the intended market. Ensure the operating temperature range meets the environmental conditions of the final application.

Resonators Selection Notes

Select this component when a precise 7.28 MHz reference is needed with tight frequency tolerance. Consider the three-pin layout for easier routing compared to two-pin alternatives. Evaluate the thermal performance to ensure operation remains within the specified -40°C to +80°C range. Compare load capacitance requirements with the host circuit design to maintain accuracy.

Resonators Part Context

This resonator belongs to the CSTCR_G series, which provides cost-effective timing solutions for digital circuits. It serves as an alternative to quartz crystals where moderate accuracy suffices. The CERALOCK branding indicates Murata's proprietary ceramic technology designed for reliability in mass-produced electronic devices.

Resonators Replacement Considerations

Direct substitutes include other Murata CSTCR series parts with matching 7.28 MHz frequency and 15 pF load capacitance. Verify pinout compatibility before replacing. Cross-reference with similar ceramic resonators from other manufacturers only if electrical parameters and physical dimensions are identical.
