CX2041NLT

Balun Overview

The CX2041NLT is an RF balun manufactured by Pulse Electronics, designed for surface-mount applications. It operates within a frequency range of 50kHz to 450MHz with a 1:1 impedance ratio between unbalanced and balanced ports. The component utilizes a 5-SMD module package. Key electrical specifications include a maximum insertion loss of 0.8dB and a minimum return loss of -25dB. It complies with RoHS3 standards and carries an EAR99 classification.

Balun Feature Summary

• Converts single-ended signals to differential signals across a wide RF bandwidth
• Provides high isolation through optimized return loss characteristics
• Supports automated assembly via standard surface-mount packaging

Balun Applications

• RF front-end circuits in wireless communication devices
• Antenna interface matching networks
• Signal processing stages requiring balanced-to-unbalanced conversion

Balun Procurement Notes

Verify the specific suffix against official datasheets to confirm performance parameters, as variants like CX2041ANLT exhibit different insertion loss values. Confirm that the 5-SMD footprint matches the target PCB layout. Ensure compliance with RoHS3 regulations is required for the specific project constraints before finalizing procurement orders.

Balun Selection Notes

Select this component when a 1:1 impedance transformation is required for frequencies extending up to 450MHz. The low insertion loss specification makes it suitable for signal integrity-sensitive designs. Consider the physical dimensions of the 5-SMD module to ensure adequate clearance on the circuit board relative to adjacent components.

Balun Part Context

This part belongs to the Pulse Electronics CX2041 series of RF baluns. It shares the same form factor and general frequency range as other members but differs in electrical performance metrics such as insertion loss. It serves as a passive transformer solution for converting between balanced and unbalanced transmission lines in radio frequency systems.

Balun Replacement Considerations

The CX2041ANLT is a related variant within the same series. Designers must verify if the higher insertion loss of the ANLT variant is acceptable for the application. No direct cross-reference substitutes are documented in the provided data.
