Overview
The RO3101E-1 is a surface-mount SAW resonator manufactured by RFMi, designed for precise frequency control in radio frequency circuits. It operates at a nominal frequency of 433.92 MHz with a stability of 10 PPM and a load capacitance of 2.5 pF. The component utilizes an SM3030-6 package measuring 3 mm x 3 mm x 1.25 mm. It supports a working voltage of 12 VDC and functions within a temperature range of -40°C to +105°C.
Feature Summary
- Surface acoustic wave technology for high-frequency stability
- Compact surface-mount design for automated assembly
- Wide operating temperature range for industrial environments
Applications
- ISM band communication systems
- Remote keyless entry systems
- Wireless sensor networks
Procurement Notes
Verify the specific suffix designation against official RFMi documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the procurement channel provides valid manufacturer traceability and authenticity certificates. Confirm compatibility with the target application's load capacitance requirements before finalizing orders.
Selection Notes
Select this component when a stable 433.92 MHz reference is required for compact RF designs. Consider the SM3030-6 footprint for space-constrained PCB layouts. Evaluate the 10 PPM stability against system phase noise requirements. Verify thermal performance within the specified -40°C to +105°C range for harsh environment deployments.
Part Context
This part belongs to the RO series of SAW resonators from RFMi, specialized for ISM band applications. It serves as a critical frequency-determining element in wireless transceivers. The device replaces older through-hole technologies with a modern surface-mount solution suitable for high-volume manufacturing processes.
Replacement Considerations
Cross-reference with Murata RO3101C or Akoustis equivalents for pin-compatible alternatives. Verify that substitute parts match the 433.92 MHz center frequency and 2.5 pF load capacitance specifications exactly.
