Antennas RF Procurement Notes

Verify the specific datasheet version for the exact gain and power ratings, as sources indicate variations between 0.79dBi/1W and 0.83dBi/2W. Confirm the package type matches the required reel or cut tape configuration for production lines. Ensure the 50-ohm impedance aligns with the RF circuit design. Check for any specific ordering suffixes that may alter performance characteristics.

Antennas RF Selection Notes

Select this component for applications requiring a low-profile UHF antenna operating specifically at 433MHz. Consider the physical dimensions of 12.3mm length when evaluating board space constraints. The 50-ohm impedance is standard for most RF interfaces. Verify that the maximum power handling meets the transmitter output requirements of the target system.

Antennas RF Part Context

This part belongs to the Pulse Electronics 1204 series of general-purpose ISM antennas. It is designed for integration into compact electronic devices where space is limited. The series supports various ISM bands including 433MHz, 868MHz, and 915MHz variants. The component serves as a direct replacement for similar ceramic chip antennas in industrial and consumer wireless applications.

Antennas RF Replacement Considerations

Direct substitutes include other 433MHz ceramic chip antennas from Pulse Electronics within the same series, such as the ANT1204LL20R0433A. When replacing, verify that the gain, impedance, and physical footprint are compatible with the existing PCB layout and RF matching network.
