CX2041ANL

Balun Overview

The CX2041ANL is an RF balun transformer manufactured by Pulse Electronics, designed for surface-mount applications. It operates within a frequency range of 50kHz to 450MHz and provides a 1:1 impedance transformation ratio between unbalanced and balanced lines. The component is housed in a compact 5-SMD module package. Key electrical specifications include a maximum insertion loss of 3.4dB and a minimum return loss of 8dB. It complies with RoHS3 standards and carries an EAR99 classification.

Balun Feature Summary

• Provides single-ended to differential signal conversion via a 1:1 impedance ratio
• Operates across a wide frequency spectrum from 50kHz to 450MHz
• Engineered for low insertion loss and high return loss performance
• Designed for direct surface-mount integration into PCB layouts

Balun Applications

• RF front-end circuits requiring balanced-to-unbalanced signal conversion
• Wireless communication systems operating in the specified frequency range
• Single-ended to differential line driving interfaces
• Signal conditioning stages in RF transceivers

Balun Procurement Notes

Verify the specific suffix designation (e.g., ANL vs ANLT) to ensure correct packaging configuration, as variants exist with different reel or tape quantities. Confirm that the 5-SMD footprint matches the target board design. Check current availability status, as supply chain conditions may affect lead times. Ensure compliance requirements such as RoHS3 are documented for the final assembly.

Balun Selection Notes

Select this component when a 1:1 impedance transformation is required for signals up to 450MHz. The 5-SMD package suits space-constrained designs. Evaluate insertion loss and return loss limits against system sensitivity requirements. Consider the operating temperature range and moisture sensitivity level (MSL 1) for reflow soldering processes. Compare physical dimensions against existing layout constraints.
