HHM1732B1

Balun Overview

The TDK HHM1732B1 is an LTCC balun transformer designed for RF signal conditioning. It operates within a frequency range of 4.9 GHz to 5.95 GHz, supporting Wi-Fi and Bluetooth applications. The component provides impedance transformation between 50 Ohms and 100 Ohms. It utilizes a surface-mount 0603 (1608 Metric) package with dimensions of 1.60mm length, 0.80mm width, and 0.60mm thickness. The device functions reliably across an operating temperature range of -40°C to +85°C.

Balun Feature Summary

• Integrates balanced-to-unbalanced conversion using Low-Temperature Co-fired Ceramic technology
• Provides precise impedance matching between differential and single-ended lines
• Supports high-frequency operation suitable for modern wireless communication standards

Balun Applications

• Wi-Fi modules
• Bluetooth transceivers
• Wireless LAN interfaces

Balun Procurement Notes

Verify the specific ordering suffix to ensure the correct variant matches the required specifications. Confirm that the component status remains active for new designs, as previous series may be obsolete. Cross-reference the datasheet parameters against the target circuit requirements before finalizing the procurement order.

Balun Selection Notes

Select this component when a compact solution is required for dual-band wireless applications. The 0603 footprint offers space efficiency for dense PCB layouts. Ensure the design accommodates the specified impedance transformation ratio and frequency bandwidth for optimal signal integrity.

Balun Part Context

This part belongs to the HHM series of LTCC baluns manufactured by TDK Corporation. It serves as a specialized passive component for RF front-end circuits, replacing discrete inductor and capacitor networks to reduce board size and improve performance consistency in consumer electronics.

Balun Replacement Considerations

The HHM1562B is listed as a recommended substitute; however, compatibility is not guaranteed. Verify electrical parameters and pinout alignment before substitution.
