RO3073A-14

Resonators Overview

The RO3073A-14 is a surface-mount SAW resonator manufactured by RFMi, operating at a nominal frequency of 315.000 MHz. It features a frequency stability of 10 PPM and a load capacitance of 4.1 pF. The device supports a maximum operating voltage of 30 VDC and functions within a temperature range of -40°C to +85°C. It utilizes the SM5035-4 package with dimensions of 5 mm in length, 3.5 mm in width, and 1.53 mm in height.

Resonators Feature Summary

• Surface-acoustic-wave (SAW) technology for stable one-port operation
• Compact surface-mount design suitable for automated assembly
• Wide industrial operating temperature range capability

Resonators Applications

• Wireless communication systems requiring 315 MHz reference
• Low-power remote keyless entry (RKE) transmitters
• Industrial control and monitoring equipment

Resonators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct frequency tolerance and package variant. Confirm that the required load capacitance matches the circuit design specifications. Check for updated RoHS compliance status directly from official documentation before finalizing procurement orders.

Resonators Selection Notes

Select this component when a precise 315 MHz surface-mount resonator is required for low-power applications. Ensure the system design accommodates the specified 4.1 pF load capacitance. Verify that the operating environment remains within the -40°C to +85°C range to maintain the stated 10 PPM frequency stability.

Resonators Part Context

This part belongs to the RO series of SAW resonators from RFMi, designed for radio frequency applications. The series provides various frequency options and package types for wireless communications. The RO3073A-14 specifically targets the 315 MHz ISM band for compact electronic solutions.

Resonators Replacement Considerations

Cross-reference with other RFMi RO3073A variants such as RO3073A-6 or RO3073A-4 if different frequency tolerances are acceptable. Ensure any substitute maintains the same SM5035-4 footprint and electrical characteristics.
