DXW21BZ7511TL

Balun Overview

The DXW21BZ7511TL is a surface-mount balun transformer manufactured by Murata Electronics, designed for signal conditioning applications. It operates within a frequency range of 50 MHz to 870 MHz and supports a maximum frequency of 1.2 GHz. The component features balanced and unbalanced impedances of 75 Ohms each, with a voltage rating of 20 V. It utilizes an SMD/SMT termination type in a compact 0805 (2012 metric) package measuring 2.0 x 1.2 x 1.2 mm. The device functions reliably across an operating temperature range from -40°C to +85°C.

Balun Feature Summary

• Ultra-miniature wire-wound microchip transformer design
• Balanced-to-unbalanced impedance conversion at 75 Ohms
• Surface-mount construction for automated assembly

Balun Applications

• RF signal conditioning circuits
• Wireless communication modules
• Broadband data transmission interfaces

Balun Procurement Notes

Verify the specific suffix 'Z' against official Murata documentation to confirm material or compliance variations compared to standard variants like 'BN'. Ensure the selected packaging format matches production requirements, as options include cut tape, reel, or MouseReel. Confirm RoHS3 compliance status directly from the manufacturer's datasheet before finalizing procurement specifications.

Balun Selection Notes

Select this component when a 75-ohm balanced-to-unbalanced transformation is required in a constrained 0805 footprint. The wide frequency range up to 1.2 GHz makes it suitable for broadband applications. Verify that the 20V voltage rating and -40°C to +85°C temperature range align with the target circuit's operational environment and stress levels.
