RO3144E-1

Overview

The Murata RO3144E-1 is a Surface Acoustic Wave (SAW) resonator operating at a center frequency of 916.5 MHz with a tolerance of +/-150 kHz. It features a single-port configuration and includes a built-in capacitor of 1.9 pF. The component exhibits an impedance of 1 MOhm and is housed in a compact 6-SMD, No Lead surface-mount package. Designed for robust performance, it supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Single-port SAW resonator architecture for precise frequency control
• Integrated built-in capacitor simplifies circuit design
• Wide industrial operating temperature range ensures reliability

Applications

• Remote control transmitters
• Data telemetry systems
• RF wireless communication circuits

Procurement Notes

Verify current availability status as the component is listed as obsolete or end-of-life by the manufacturer. Confirm that the 6-SMD package matches your PCB footprint requirements. Ensure the 916.5 MHz frequency aligns with your specific regulatory and operational standards before finalizing procurement plans.

Selection Notes

Select this component when a stable 916.5 MHz reference is required for remote control or telemetry applications. The integrated capacitor reduces external component count. Consider the wide temperature range if the device operates in harsh environments. Verify compatibility with existing RF front-end designs due to the single-port topology.

Part Context

This SAW resonator belongs to Murata's line of frequency control devices intended for ISM band applications. It serves as a critical timing element in low-power wireless transmitters. The technology leverages surface acoustic wave propagation to achieve high stability in a miniature surface-mount form factor suitable for modern electronics.

Replacement Considerations

As the part is marked obsolete, direct substitutes may be limited. Check Murata's official discontinuation notices for recommended replacement part numbers. Evaluate alternative SAW resonators from other manufacturers offering similar 916.5 MHz specifications and compatible SMD packages.
