Antennas RF Procurement Notes

Verify the specific suffix and revision level against the manufacturer's latest datasheet before ordering. Confirm that the required packaging format matches your assembly line capabilities. Ensure the component meets all RoHS compliance requirements for your target market. Cross-reference the part number with official distributor catalogs to avoid obsolete stock or incorrect substitutions.

Antennas RF Selection Notes

Select this component when space constraints require the smallest available GNSS antenna solution. The 1206 package allows for high-density PCB layouts in portable electronics. Consider the 2.4 dBi gain and 50 Ohm impedance for standard RF matching networks. Evaluate the -40°C to +85°C operating range against environmental conditions.

Antennas RF Part Context

This antenna belongs to Taiyo Yuden's RadiEdge series, which focuses on miniaturization for wireless components. The AH316M157501-T represents a significant reduction in volume and height compared to earlier models like the AF816M157502. It is categorized under PCB antennas and is intended for general electronic equipment requiring satellite positioning capabilities.

Antennas RF Replacement Considerations

Public documentation suggests TSA5NA2K1G57NS001T as a suggested alternate part. Verify electrical compatibility and mechanical fit before substitution.
