HHM1541E1

Balun Overview

The HHM1541E1 is a surface-mount RF balun manufactured by TDK Corporation, designed for Bluetooth applications operating at 2.4 GHz. It features an unbalanced port with a nominal characteristic impedance of 50 Ohms and a balanced port with a nominal characteristic impedance of 75 Ohms. The component supports a frequency range of 2.3 GHz to 2.5 GHz with a bandwidth of 100 MHz. It is housed in an 0805 (2012 Metric) package.

Balun Feature Summary

• Integrates unbalanced-to-balanced signal conversion for RF circuits
• Optimized for Bluetooth communication systems
• Supports standard 50-Ohm and 75-Ohm impedance configurations

Balun Applications

• Bluetooth module integration
• RF signal conditioning circuits
• Wireless communication devices

Balun Procurement Notes

Verify the specific datasheet version and impedance parameters against the latest official TDK documentation before integration. Confirm that the 50/75 Ohm configuration aligns with the target circuit design requirements. Ensure compliance with RoHS standards and check for any recent supply chain updates or alternative package options if necessary.

Balun Selection Notes

Select this component when a compact solution for Bluetooth signal balancing is required within the 2.3–2.5 GHz spectrum. The 0805 footprint suits space-constrained designs. Consider the specific impedance mismatch between the 50-Ohm unbalanced side and 75-Ohm balanced side during schematic design to ensure optimal signal integrity.

Balun Part Context

This part belongs to TDK's portfolio of passive RF components, specifically baluns used for impedance transformation and phase inversion. It complements other RF filters and matching networks in wireless transceiver front-ends. The component is distinct from TDK's capacitors and inductors, focusing solely on differential signal processing.

Balun Replacement Considerations

Consult official TDK substitution guides for compatible baluns with similar impedance ratios and frequency ranges. Verify pin compatibility and thermal characteristics before replacing with generic equivalents.
