RO3103A-1

Overview

The RO3103A-1 is a surface-mount SAW resonator manufactured by RFMi, operating at a nominal frequency of 418.000 MHz. It features a frequency tolerance of ±75 kHz and maintains high stability with a drift of 32 parts per billion (ppb). The component is designed for robust performance across an extended temperature range of -40°C to +125°C. With a load capacitance of 2.7 pF, it supports precise signal generation in wireless communication systems requiring reliable frequency control.

Feature Summary

Surface mount construction optimized for reflow soldering processes
High frequency stability suitable for demanding wireless applications
Extended operational temperature range ensuring reliability in varied environments

Applications

Wireless communications devices
Digital signal processing circuits
Frequency reference modules

Procurement Notes

Verify the specific ordering suffix and package variant against the official Akoustis/RFMi datasheet to ensure compatibility with your assembly process. Confirm that the 418 MHz frequency and 32 ppb stability meet your system requirements before finalizing procurement orders.

Selection Notes

Select this component when a stable 418 MHz reference is required in space-constrained designs. The surface-mount format facilitates automated assembly. Ensure the thermal profile of your manufacturing line supports the specified -40°C to +125°C operating range for long-term reliability.

Part Context

This part belongs to the RFMi family of radio frequency components, which includes SAW, crystal, and ceramic technologies. RFMi, now part of Akoustis, specializes in high-performance filters and resonators for digital and wireless markets, providing essential passive components for modern communication hardware.

Replacement Considerations

Consult the manufacturer's cross-reference guide for direct substitutes. Verify that any alternative part matches the 418 MHz frequency, 2.7 pF load capacitance, and surface-mount footprint to maintain circuit integrity without redesign.
