ANT-BEAD-86890

Antennas RF Overview

The ANT-BEAD-86890 is a miniature bead antenna manufactured by RF Solutions, designed for UHF frequency applications. It operates at a center frequency of 868MHz within the ISM band. The component features a through-hole mounting type with solder termination, suitable for compact PCB integration. Key electrical specifications include a Voltage Standing Wave Ratio (VSWR) of 2 and an echo loss of -15dB. The antenna provides 0dBi gain and covers a single frequency band. Physical dimensions include a maximum height of 9.00mm (0.354 inches). This part is classified as obsolete and no longer in production.

Antennas RF Feature Summary

• Compact bead design optimized for space-constrained PCB mounting solutions
• Through-hole solder termination ensures secure mechanical and electrical connection
• Single-band operation centered at 868MHz for specific regional ISM compliance

Antennas RF Applications

• UHF wireless sensor networks requiring compact antenna profiles
• ISM band communication devices operating at 868MHz
• IoT modules where low-profile through-hole antennas are preferred

Antennas RF Procurement Notes

This component is officially marked as obsolete and no longer manufactured by RF Solutions. Procurement must rely on existing stock or authorized distributors holding legacy inventory. Verify part authenticity carefully due to end-of-life status. Direct replacement options should be evaluated if long-term supply assurance is required for production cycles.

Antennas RF Selection Notes

Select this antenna only for projects utilizing through-hole assembly processes and requiring 868MHz coverage. Ensure PCB footprint compatibility with the specified bead form factor. Consider the VSWR of 2 when designing matching circuits. Due to obsolescence, verify availability constraints before finalizing the design for mass production.

Antennas RF Part Context

The ANT-BEAD series represents RF Solutions' line of miniature bead antennas intended for general-purpose RF applications. The ANT-BEAD-86890 specifically targets the European ISM band. It belongs to the broader category of UHF antennas but is distinct due to its specific 868MHz tuning and through-hole construction method compared to surface-mount alternatives.

Antennas RF Replacement Considerations

The direct substitute part number is ANT-BEAD-GSM90 from RF Solutions. This alternative offers similar form factors and functionality. Verify that the GSM90 variant meets the specific regulatory and frequency requirements of the target application before substitution.
