Antennas RF Procurement Notes

Verify the specific datasheet version to confirm mechanical dimensions and impedance matching requirements. Ensure the SMA connector gender matches the host device interface. Check RoHS compliance status against current regulatory standards for the target market.

Antennas RF Selection Notes

Select this component when a low-profile helical antenna is required for 433 MHz operations. Consider the 44 mm length constraint during enclosure design. Verify that the 2.5 dBi gain meets the link budget requirements for the intended application range.

Antennas RF Part Context

This model belongs to the RF Solutions passive antenna portfolio, specifically targeting indoor and short-range UHF applications. It complements other whip and helical variants in the manufacturer's lineup for diverse mounting and performance needs.

Antennas RF Replacement Considerations

Cross-reference with ANT-433WM3-SMA for similar frequency bands but different physical form factors. Ensure compatibility with existing SMA interfaces when substituting.
