FI168T155021-T

Balun Overview

The FI168T155021-T is a surface-mount RF balun manufactured by Taiyo Yuden, designed for signal conditioning in high-frequency applications. It operates within a frequency range of 900 MHz to 2.2 GHz and supports an impedance configuration of 50 Ohms unbalanced to 75 Ohms balanced. The component features a maximum insertion loss of 2.3 dB and is housed in a compact 0603 (1608 metric) package with three PCB pads. This device facilitates efficient RF signal transmission between balanced and unbalanced circuits.

Balun Feature Summary

• Converts signals between 50-ohm unbalanced and 75-ohm balanced lines
• Operates across a wide frequency spectrum from 900 MHz to 2.2 GHz
• Utilizes a compact 0603 surface-mount footprint for space-constrained designs

Balun Applications

• Wireless communication systems requiring impedance transformation
• RF front-end modules in mobile devices
• Antenna interface circuits in consumer electronics

Balun Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Taiyo Yuden or authorized distributors before procurement. Confirm that the 50/75 Ohm impedance specification aligns precisely with the target circuit design requirements. Ensure the 0603 package dimensions are compatible with the intended PCB layout and manufacturing processes.

Balun Selection Notes

Select this component when a transition from 50-ohm unbalanced sources to 75-ohm balanced loads is required within the 900 MHz to 2.2 GHz band. Consider the 2.3 dB insertion loss limit against system power budget constraints. The 0603 size makes it suitable for dense layouts where larger baluns cannot fit, provided the thermal and mechanical handling capabilities meet assembly standards.

Balun Part Context

This part belongs to the FI series of high-frequency devices from Taiyo Yuden, which specializes in SAW and FBAR technologies for mobile communications. The FI168T155021-T specifically addresses the need for compact baluns in modern wireless infrastructure and portable devices, supporting the industry trend toward miniaturization while maintaining signal integrity at UHF and lower microwave frequencies.

Balun Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Evaluate alternative baluns based on matching frequency range, impedance ratios, and package dimensions if this component is unavailable.
