2-1-1WL

Overview

The Bourns Inc. 2-1-1WL is a compact radio frequency balun designed for signal transmission applications within the 50kHz to 200MHz frequency range. This component features a 1:1 impedance ratio between its unbalanced and balanced ports, ensuring efficient energy transfer. It is housed in a 6-SMD surface-mount package with gull-wing leads, facilitating automated assembly and integration into space-constrained circuit boards. The device operates as an active part within the manufacturer's lineup of passive components.

Feature Summary

• Provides balanced-to-unbalanced signal conversion for RF circuits
• Supports transmission frequencies from 50kHz up to 200MHz
• Features a 1:1 impedance transformation ratio
• Utilizes a compact 6-SMD gull-wing surface-mount package

Applications

• RF signal transmission systems
• Compact radio frequency circuit design
• Space-constrained electronic assemblies requiring surface-mount baluns

Procurement Notes

Verify the specific datasheet version when sourcing this component, as manufacturers may update specifications over time. Confirm that the 6-SMD gull-wing package matches your PCB footprint requirements. Ensure that the 50kHz to 200MHz operational range aligns with your system's frequency needs. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select the 2-1-1WL when a 1:1 impedance balance is required for frequencies extending up to 200MHz. Consider this component for designs prioritizing a small surface-mount footprint. Evaluate the gull-wing lead style against your assembly capabilities. Compare performance against other baluns in the series if wider bandwidth or different impedance ratios are necessary.

Part Context

This component belongs to Bourns' family of radio frequency baluns, which are essential for converting single-ended signals to differential signals. The 2-1-1WL specifically addresses applications needing a 1:1 ratio within the lower RF spectrum. It complements other passive components like resistors and inductors in power and signal conditioning circuits.

Replacement Considerations

The 3-1.5-1WL is a related model offering a 100kHz to 300MHz range. Verify compatibility before substitution, as frequency ranges and impedance characteristics differ. Other variants in the series may offer different pin configurations or ratios.
