HHM17146A1

Balun Overview

The TDK HHM17146A1 is an RF balun operating within the 1.92GHz to 2.17GHz frequency range. It provides a 50/50 Ohm impedance transformation between unbalanced and balanced ports. The component features a maximum insertion loss of 1.0dB and a minimum return loss of 10dB, with a phase difference of 180° ±10°. Packaged in a compact 0805 (2012 metric) surface-mount housing with six PCB pads, it supports RoHS3 compliance and MSL level 1 moisture sensitivity.

Balun Feature Summary

• Converts single-ended signals to differential signals for RF applications
• Maintains signal integrity through controlled impedance matching
• Ensures phase coherence with specified phase difference tolerance

Balun Applications

• Wireless LAN modules
• Bluetooth transceivers
• RF front-end circuits

Balun Procurement Notes

Verify current availability as the part status is listed as Not Recommended for New Designs. Confirm that the selected packaging option aligns with automated assembly requirements. Check for potential minimum order quantity restrictions associated with the discontinued status before finalizing procurement plans.

Balun Selection Notes

Select this component when designing for the 1.92GHz to 2.17GHz band requiring 50-ohm impedance balance. Ensure the 0805 footprint fits the layout constraints. Consider the Not Recommended for New Design status and evaluate long-term supply chain stability against alternative active components.

Balun Part Context

This device belongs to the HHM series of baluns from TDK Corporation. It is designed for high-frequency signal processing where size and performance are critical. The component utilizes ceramic technology suitable for surface-mount integration in modern electronic devices.

Balun Replacement Considerations

The HHM17146A1 is not recommended for new designs. The manufacturer recommends the HHM17144A1 as a substitute. Verify compatibility regarding frequency range and package dimensions before substitution.
