CSTNR4M91GH5C000R0

Resonators Overview

The Murata Electronics CSTNR4M91GH5C000R0 is a CERALOCK ceramic resonator designed for surface mount applications. It operates at a nominal frequency of 4.915 MHz with an initial tolerance of ±0.07%. The component features a built-in load capacitance of 39 pF, eliminating the need for external capacitors in oscillator circuits. It utilizes a three-terminal SMD package measuring 4.5 mm in length, 2.0 mm in width, and 1.1 mm in height. The device supports a wide operating temperature range from -40°C to +125°C, ensuring reliability in demanding environments.

Resonators Feature Summary

• Integrated 39 pF load capacitance simplifies circuit design by removing the requirement for external capacitors.

Resonators Applications

• Microcontroller clock sources
• Communication module timing
• Consumer electronics oscillators

Resonators Procurement Notes

Verify the specific suffix GH5C000R0 against the target schematic requirements to ensure compatibility with the intended oscillator circuit topology. Confirm that the 39 pF internal capacitance aligns with the microcontroller's specified load capacitance needs. Check RoHS compliance status if restricted substances are a concern for the final assembly process.

Resonators Selection Notes

Select this component when a stable 4.915 MHz reference is required with minimal external passive components. The high-temperature rating up to 125°C makes it suitable for industrial or automotive infotainment applications where standard commercial grade parts may fail. Ensure the PCB footprint matches the 4.5x2.0x1.1mm dimensions provided in the mechanical drawing.

Resonators Part Context

This part belongs to the CSTNR series of CERALOCK ceramic resonators, which are known for their compact size and high stability compared to traditional LC oscillators. The series offers various frequencies and tolerance levels to suit different timing requirements in embedded systems.

Resonators Replacement Considerations

Direct substitutes must match the 4.915 MHz frequency, 39 pF load capacitance, and ±0.07% tolerance. Verify pinout compatibility and thermal characteristics before swapping manufacturers.
