2-4-1DL

Overview

The Bourns Inc. 2-4-1DL is a magnetic RF transformer, specifically designed as a balun for signal conversion applications. It operates within a frequency range of 200 kHz to 350 MHz, ensuring effective performance across this specified bandwidth. The component features a primary-to-secondary turns ratio of 1:2 and maintains a maximum insertion loss of 3.0 dB, which supports efficient signal transmission with minimal attenuation. It is housed in a standard 6-DIP package with a lead pitch of 0.300 inches (7.62 mm), facilitating integration into various circuit layouts.

Feature Summary

• Functions as a balanced-to-unbalanced converter (balun) for RF signal processing
• Provides electrical isolation and impedance matching between circuit stages
• Constructed with magnetic core technology for stable RF transformer operation

Applications

• RF signal balancing and unbalancing in communication circuits
• Impedance transformation in radio frequency amplifier stages
• Signal coupling in broadband transformer applications

Procurement Notes

Verify the specific datasheet version corresponding to the 2-4-1DL part number to confirm exact electrical tolerances and pinout configurations. Ensure that the 6-DIP package dimensions align with the target PCB footprint requirements. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the manufacturer's official documentation for any updates regarding material composition or manufacturing changes.

Selection Notes

Select this component when a 1:2 turns ratio is required for balancing signals within the 200 kHz to 350 MHz frequency band. Consider the 3.0 dB maximum insertion loss limit to ensure it meets system sensitivity requirements. The 6-DIP package is suitable for through-hole mounting processes. Evaluate the physical size constraints against the 0.300-inch lead pitch to ensure adequate spacing on the printed circuit board.
