BW21S5011A01TF

Balun Overview

The BW21S5011A01TF is a surface-mount RF balun manufactured by Shenzhen Sunlord Electronics Co., Ltd. It operates within a frequency range of 45 MHz to 870 MHz and features balanced and unbalanced impedances of 50 Ohms each. The component utilizes an 0805 (2012 Metric) package, providing a compact form factor suitable for space-constrained designs. Key electrical specifications include a maximum insertion loss of 1.2 dB, common mode rejection of 20 dB, and a power handling capacity of 27 dBm.

Balun Feature Summary

• Provides impedance transformation between balanced and unbalanced signal paths
• Designed for high-frequency radio frequency applications
• Utilizes a compact surface-mount footprint

Balun Applications

• Wireless communication systems
• Mobile device antenna interfaces
• RF front-end modules

Balun Procurement Notes

Verify the specific datasheet version with the manufacturer prior to ordering, as product specifications may be subject to revision. Confirm that the 0805 package dimensions align with your PCB layout requirements. Ensure that the operating temperature range meets your system's environmental conditions. Cross-reference the part number with authorized distributors to confirm current availability and lead times. Validate that the component complies with relevant industry standards for your target market.

Balun Selection Notes

Select this component when a 50-ohm balanced-to-unbalanced conversion is required in the 45 MHz to 870 MHz range. Consider the 0805 package size if board space is limited. Evaluate the 1.2 dB insertion loss against system sensitivity requirements. Assess the 27 dBm power handling capability to ensure it exceeds the maximum expected signal levels. Compare common mode rejection performance with alternative baluns for noise immunity needs.
