HHM1517

Balun Overview

The HHM1517 is a surface mount RF/IF and RFID component manufactured by TDK Corporation. It functions as an unbalanced-to-balanced transformer (balun) designed for wireless applications. The device operates within a frequency range of 2.4 GHz to 2.5 GHz, supporting standard 50 Ohm impedance systems. It utilizes a 50 / 50 Ohm configuration to facilitate signal conversion between balanced and unbalanced lines. The component is housed in a compact 0805 (2012 Metric) package, suitable for automated assembly processes.

Balun Feature Summary

• Provides balanced-to-unbalanced signal transformation for RF circuits
• Operates within the 2.4 GHz to 2.5 GHz frequency band
• Supports 50 Ohm impedance matching for both balanced and unbalanced ports

Balun Applications

• Wireless LAN modules
• Bluetooth low energy transceivers
• RFID reader interfaces

Balun Procurement Notes

Verify that the specific part number matches the required 0805 package dimensions and impedance specifications. Confirm the manufacturer source is TDK Corporation or an authorized distributor to ensure authenticity. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure storage conditions align with moisture sensitivity level requirements before soldering.

Balun Selection Notes

Select this component when a compact solution is needed for 2.4 GHz ISM band applications requiring impedance transformation. The 0805 footprint allows for high-density PCB layouts. Consider thermal management capabilities during layout design. Verify that the insertion loss and return loss characteristics meet the system's signal integrity requirements for the specific frequency range.

Balun Part Context

This balun belongs to TDK's portfolio of passive RF components used in modern wireless communication devices. It addresses the need for efficient signal conversion in space-constrained mobile electronics. The component supports the integration of wireless connectivity features into consumer gadgets and industrial sensors without compromising board real estate.

Balun Replacement Considerations

Consult official TDK documentation for verified substitute part numbers. Do not assume cross-compatibility with other manufacturers' baluns due to potential differences in impedance matching and frequency response characteristics.
