RO3118E-1

Overview

The RO3118E-1 is a surface-mount SAW resonator manufactured by RFMi, an Akoustis brand. It operates at a center frequency of 318.05 MHz with a frequency stability of 32 ppb. The component utilizes a 6-SMD, No Lead package measuring 3.00mm x 3.00mm (0.118" L x 0.118" W). Designed for use as a frequency control element in transmitters, it supports a working power supply voltage of 12 VDC and functions within a temperature range of -40°C to +105°C.

Feature Summary

• Surface-mount SAW technology for compact integration
• High frequency stability of 32 ppb
• Wide operating temperature range from -40°C to +105°C

Applications

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

Procurement Notes

Verify the specific ordering suffix and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the 6-SMD no-lead package dimensions align with your PCB footprint requirements. Ensure the 12 VDC operating voltage specification matches your circuit design constraints. Cross-reference the 318.05 MHz frequency tolerance against your system's strict stability needs.

Selection Notes

Select this component when a surface-mount SAW resonator is required for transmitter applications needing high stability. The 3.00mm x 3.00mm package size suits space-constrained designs. Consider the wide temperature range if the device will operate in harsh environments. Verify compatibility with existing oscillator circuits designed for single-port or dual-port resonator inputs.
