RO3120C

Overview

The RO3120C is a surface-mount SAW resonator manufactured by RFMi, an Akoustis brand. It operates at a center frequency of 403.550 MHz and is housed in an 8-SMD, No Lead package with dimensions of 5.00mm x 5.00mm. The component utilizes quartz frequency stabilization within a hermetically sealed ceramic package to ensure reliability. It complies with RoHS standards and meets the AEC-Q200 automotive qualification requirements, making it suitable for demanding wireless applications.

Feature Summary

• Hermetically sealed ceramic package for environmental protection
• Quartz-based frequency stabilization technology
• AEC-Q200 qualified for automotive reliability standards
• RoHS compliant construction

Applications

• Frequency control elements in transmitters
• Wireless communication devices
• OEM equipment requiring internet connectivity and remote monitoring

Procurement Notes

Verify the specific manufacturing date code and lot traceability upon receipt to ensure compliance with AEC-Q200 automotive standards. Confirm that the delivered units match the 403.550 MHz specification and 8-SMD package dimensions. Check for any special handling requirements related to the hermetic seal integrity during storage and assembly processes.

Selection Notes

Select this component when a stable, high-reliability frequency reference is required for transmitter circuits operating near 403 MHz. The AEC-Q200 qualification makes it appropriate for automotive or industrial environments where long-term stability and harsh condition resistance are critical. Ensure the system design accommodates the 5.00mm x 5.00mm surface mount footprint.
