HHM17139B2

Balun Overview

The HHM17139B2 is an RF balun manufactured by TDK Corporation, designed for operation within the 2.4GHz to 2.6GHz frequency range. It provides a balanced-to-unbalanced impedance transformation with a nominal ratio of 50/50 Ohms. The component features a maximum insertion loss of 0.4dB and a phase difference of 178 degrees. It is housed in a compact 0603 (1608 metric) surface-mount package with six printed circuit board pads. The device is RoHS3 compliant and classified under ECCN EAR99.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion for RF applications
• Optimized for 2.4GHz to 2.6GHz wireless communication bands
• Compact 0603 surface-mount footprint for space-constrained designs

Balun Applications

• Wireless LAN modules operating in ISM bands
• Bluetooth low energy transceivers
• Zigbee and other 2.4GHz IoT connectivity devices

Balun Procurement Notes

Verify the specific ordering suffix required for your packaging needs, such as tape and reel or cut tape options. Confirm that the 0603 pad layout matches your PCB design guidelines. Ensure compliance with RoHS3 standards if applicable to your region. Check moisture sensitivity level requirements for your reflow soldering profile.

Balun Selection Notes

Select this component when a 50-ohm unbalanced interface must connect to a 50-ohm balanced antenna or filter. The 0.4dB insertion loss specification supports high-efficiency signal transmission. The 178-degree phase difference indicates close-to-ideal balance performance. Consider the 0603 size constraint against available board real estate.

Balun Part Context

This part belongs to the TDK HHM series of RF baluns. These components are engineered for miniaturization while maintaining stable electrical characteristics across the specified frequency band. The series supports various impedance ratios and frequency ranges for diverse wireless standards.

Balun Replacement Considerations

Consult official substitution lists for verified equivalents. Generic replacements may differ in phase balance or insertion loss specifications.
