2-4-6WEL

Overview

The Bourns Inc. 2-4-6WEL is a surface mount BALUN transformer designed for RF applications. It operates within a frequency range of 20 kHz to 250 MHz and provides a 1:4 unbalanced-to-balanced impedance transformation ratio. The component utilizes a 6-SMD GW package configuration. Key electrical specifications include a maximum insertion loss of 3.0 dB, ensuring efficient signal transmission across its designated bandwidth.

Feature Summary

• Provides 1:4 unbalanced to balanced impedance conversion
• Operates effectively from 20 kHz to 250 MHz
• Designed for surface mount integration

Applications

• RF circuit balancing
• Signal transmission systems
• Communication equipment interfaces

Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm the exact pinout and mechanical dimensions for the 6-SMD GW package. Ensure that the operating frequency requirements align with the 20 kHz to 250 MHz specification before procurement. Cross-reference the part number 2-4-6WEL with official Bourns catalogs to validate authenticity and current production status.

Selection Notes

Select this component when a compact surface mount solution is required for converting single-ended signals to differential signals in the specified frequency range. Consider the 3.0 dB maximum insertion loss limit when designing for high-efficiency signal paths. Evaluate the physical footprint constraints against the 6-SMD GW package size to ensure compatibility with the target PCB layout.

Part Context

This BALUN is part of Bourns' passive component portfolio, which includes resistors, capacitors, and inductors. It serves as a specialized interface device for managing signal integrity between unbalanced and balanced network segments. The product supports various electronic applications requiring reliable impedance matching and signal conversion without active power sources.

Replacement Considerations

Consult official Bourns substitution guides or equivalent manufacturer catalogs for compatible alternatives. Verify that any substitute maintains the 1:4 ratio and 20 kHz–250 MHz operational range. Ensure the replacement package matches the 6-SMD form factor for direct board compatibility.
