2-2-1JEL

Overview

The Bourns Inc. 2-2-1JEL is a surface-mount RF transformer, specifically designed as a balun component. It operates within a frequency range of 70 kHz to 200 MHz. The device utilizes a 6-SMD J-Lead package configuration for integration into printed circuit boards. This magnetic component facilitates signal conversion in radio frequency circuits.

Feature Summary

• Functions as a balanced-to-unbalanced (balun) transformer for RF signal processing
• Supports operation across a wide frequency spectrum from 70 kHz to 200 MHz
• Utilizes a compact surface-mount J-Lead package design

Applications

• RF communication systems requiring impedance matching and signal conversion
• Wireless transmission modules operating within the specified frequency band
• Radio frequency front-end circuits in consumer electronics

Procurement Notes

Verify the specific datasheet version for the 2-2-1JEL to confirm exact electrical parameters such as insertion loss and return loss. Ensure compatibility with the target PCB footprint for the 6-SMD J-Lead package. Confirm RoHS compliance status if required by the end-product specifications. Cross-reference the manufacturer's official documentation for any recent design changes or obsolescence notices before finalizing procurement.

Selection Notes

Select this component when a surface-mount balun solution is required for frequencies up to 200 MHz. The J-Lead package offers a compact form factor suitable for space-constrained designs. Consider the thermal and mechanical requirements of the application to ensure the surface-mount technology meets the reliability standards. Evaluate the need for high-frequency performance characteristics against other available RF transformers in the Bourns portfolio.

Part Context

This component belongs to the category of magnetics and RF transformers manufactured by Bourns Inc. Baluns are essential passive components used to interface balanced lines with unbalanced lines, ensuring proper signal integrity in RF applications. The 2-2-1JEL represents a specific implementation optimized for surface-mount assembly processes.

Replacement Considerations

Consult the official Bourns Inc. replacement guide or distributor cross-reference tools to identify equivalent balun components. Verify that any substitute part matches the 70 kHz to 200 MHz frequency range and the 6-SMD J-Lead package dimensions. Ensure electrical performance metrics align with the original design requirements.
