748425245

Balun Overview

The Würth Elektronik 748425245 is a multilayer SMD chip balun designed for RF applications and wireless communication systems. It operates within the frequency range of 2.4GHz to 2.5GHz, making it suitable for ISM band usage. The component provides an impedance transformation from 50 Ohms unbalanced to 50 Ohms balanced. It features a phase difference of 180° ±10° and a maximum insertion loss of 1.0dB. The device is housed in a compact 0805 (2012 metric) surface-mount package.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion for RF circuits
• Designed specifically for 2.4GHz to 2.5GHz wireless communication bands
• Utilizes multilayer technology for compact surface-mount integration

Balun Applications

• RF front-end modules in wireless communication devices
• ISM band antenna interface circuits
• Bluetooth and Wi-Fi transceiver designs

Balun Procurement Notes

Verify the specific ordering suffix required for your production volume, as availability varies between cut tape, reel, and Digi-Reel formats. Confirm that the 0805 footprint matches your PCB layout constraints. Ensure compliance with RoHS3 standards if required by your environmental regulations. Check current factory lead times, which may extend up to 18 weeks depending on supply chain conditions.

Balun Selection Notes

Select this component when a 50-ohm to 50-ohm impedance match is required at 2.4GHz. Consider the 0805 package size for space-constrained layouts. Evaluate the 1.0dB insertion loss against system budget requirements. Ensure the design accounts for potential center frequency shifts due to PCB parasitic effects, as recommended in manufacturer guidelines.
