CX2045LNL

Balun Overview

The CX2045LNL is an RF balun manufactured by Pulse Electronics, designed for wideband applications. It operates within a frequency range of 3MHz to 300MHz and provides a 1:2 impedance transformation ratio between unbalanced and balanced ports. The component features a maximum insertion loss of 0.8dB and utilizes a nonstandard surface mount package. It is RoHS3 compliant and classified under EAR99 with a Moisture Sensitivity Level of 1.

Balun Feature Summary

• Provides 1:2 impedance transformation for RF signal balancing
• Operates across a wide frequency spectrum from 3MHz to 300MHz
• Designed for surface mount integration in compact circuits

Balun Applications

• Wideband RF transformer circuits
• RF signal balancing interfaces
• Miniature surface mount electronic assemblies

Balun Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may contain updated electrical tolerances or mechanical drawings. Confirm that the nonstandard SMD package dimensions align with your PCB footprint requirements prior to assembly. Ensure compliance with RoHS3 standards if required by your environmental regulations. Cross-reference the part number with official distributor catalogs to confirm current availability status.

Balun Selection Notes

Select this component when a 1:2 impedance ratio is required for frequencies up to 300MHz. The low insertion loss specification supports efficient signal transmission in sensitive RF paths. Consider the nonstandard package size during layout planning to ensure adequate clearance. This part is suitable for designs prioritizing wideband performance over narrowband tuning capabilities.

Balun Part Context

This component belongs to the CX series of audio and signal transformers produced by Pulse Electronics. It is categorized under RF transformers and is distinct from other models in the lineup by its specific 1:2 transformation ratio and broad frequency coverage. The series generally targets miniature surface mount applications requiring reliable RF signal conversion.

Balun Replacement Considerations

The CX2047LNL is a documented substitute within the same product family, offering different impedance ratios such as 1:4CT or 1:2CT. Verify that the alternative part's frequency range and physical dimensions are compatible with the existing design constraints before substitution.
