Procurement Notes

Verify the specific manufacturer part number against official Murata documentation to ensure authenticity. Confirm that the device meets the required RoHS compliance standards for your region. Check the datasheet for the exact package dimensions and soldering profile recommendations to ensure compatibility with your manufacturing process. Ensure the supplier provides valid traceability documents.

Selection Notes

Select this component when a fixed frequency source near 433.92 MHz is required with high precision. Consider the 1 MOhm series resistance impact on circuit loading. Evaluate the thermal performance within the specified -40°C to +85°C range for your application environment. Compare against other SAW resonators if different mounting styles or wider temperature ranges are necessary.

Part Context

This component belongs to the family of high-frequency passive devices used in RF front-ends. Murata Electronics produces various SAW resonators for global wireless standards. The RO3102A specifically targets markets requiring reliable oscillation without active tuning components, serving as a fundamental building block for transmitter and receiver stages in low-power wireless devices.

Replacement Considerations

The RO3101C is documented as a similar specification part from Murata Electronics North America. Verify pinout compatibility and electrical parameters before substitution.
