HHM1726N1

Balun Overview

The TDK HHM1726N1 is a surface-mount RF balun designed for the 824MHz to 915MHz frequency range. It features a 50/100 Ohm impedance configuration and operates within a 0603 (1608 metric) package footprint. The component specifies a maximum insertion loss of 0.8dB and a minimum return loss of -10dB, with a phase difference of 180° ±10°. Packaged in tape and reel format, this device supports high-volume automated assembly processes.

Balun Feature Summary

• Converts unbalanced signals to balanced signals within the specified ISM band frequencies
• Maintains signal integrity through low insertion loss characteristics
• Utilizes a compact surface-mount form factor for space-constrained PCB layouts

Balun Applications

• ISM band wireless communication modules
• RF front-end circuitry for transceivers
• Balanced-to-unbalanced signal conversion interfaces

Balun Procurement Notes

Verify current availability status as the manufacturer has indicated this part number is obsolete or end-of-life. Confirm if the recommended substitute HHM17144A1 meets all original design requirements before procurement. Check datasheet revisions for any parameter changes in replacement components.

Balun Selection Notes

Select this component for applications requiring precise 180-degree phase shifting in the 824-915MHz range. Ensure the PCB layout accommodates the specific 0603 pad configuration. Consider the impedance matching between the 50 Ohm and 100 Ohm ports to optimize signal transfer efficiency.

Balun Part Context

This component belongs to the TDK HHM series of RF baluns. It is specifically engineered for radio frequency signal conditioning tasks where size reduction and performance stability are critical. The series typically offers various impedance options tailored for different wireless standards.

Balun Replacement Considerations

The manufacturer recommends the HHM17144A1 as a direct substitute. Verify that the substitute maintains identical frequency coverage and impedance specifications to ensure circuit compatibility without redesign.
