2-2-1DL

Overview

The Bourns 2-2-1DL is a broadband transformer, specifically configured as a balun, designed for signal conversion between balanced and unbalanced lines. It operates within a frequency range of 70 kHz to 200 MHz. The component is housed in a compact 6-DIP package, suitable for surface mount or through-hole integration depending on the specific variant configuration. It is manufactured by Bourns, Inc., a provider of discrete semiconductor and passive electronic components.

Feature Summary

• Functions as a broadband balun for impedance matching and signal transformation
• Operates across a wide frequency spectrum from 70 kHz to 200 MHz
• Utilizes a standard 6-DIP package format for circuit board integration

Applications

• RF and wireless communication circuits
• Signal processing interfaces requiring balanced-to-unbalanced conversion
• Broadband transformer applications in electronic testing equipment

Procurement Notes

Verify the exact datasheet specifications for insertion loss and return loss parameters prior to integration. Confirm that the 6-DIP package dimensions align with the target PCB footprint. Ensure compliance with RoHS standards if required by the final product assembly. Cross-reference the manufacturer part number to avoid confusion with similar series variants.

Selection Notes

Select this component when a fixed frequency range of 70 kHz to 200 MHz is required for balun functionality. Consider the 6-DIP form factor for mechanical stability in high-vibration environments. Evaluate the need for broadband performance over narrowband tuned transformers. Verify thermal requirements against the operating environment of the host system.

Part Context

This component belongs to Bourns' portfolio of magnetic components and RF transformers. It is distinct from their resistor, potentiometer, and protection device lines. The 2-2-1DL designation identifies a specific balun configuration within their broader catalog of signal integrity solutions.

Replacement Considerations

Consult official Bourns documentation for direct cross-references. Similar models may include variations in frequency range or package style. Do not assume interchangeability without verifying electrical parameters such as impedance ratio and bandwidth.
