NCS2-33+

Balun Overview

The NCS2-33+ is a surface-mount RF transformer manufactured by Mini-Circuits, designed for balanced-to-unbalanced signal conversion. It operates within a frequency range of 1.5 GHz to 3.1 GHz with a 1:2 impedance ratio. Key electrical specifications include a maximum insertion loss of 1.0 dB and a minimum return loss of 14.72 dB. The device maintains a phase difference of 5 degrees and utilizes a compact 6-SMD, no-lead package suitable for high-density PCB layouts.

Balun Procurement Notes

Verify the component datasheet against the specific manufacturing lot date code to ensure compliance with recent material changes. Confirm that the 6-SMD footprint matches the target PCB design constraints. Check RoHS and REACH status documentation for regulatory adherence in the destination market. Ensure storage conditions align with moisture sensitivity level requirements prior to assembly.

Balun Selection Notes

Select this component when a 1:2 impedance transformation is required between 1.5 GHz and 3.1 GHz. Consider the 6-SMD package size for board space limitations. Evaluate insertion loss and phase balance requirements against system noise floor and signal integrity needs. Compare physical dimensions against available layout area to confirm fitment without mechanical interference.

Balun Part Context

This part belongs to the Mini-Circuits RF transformer family, specifically engineered for microwave and radio frequency applications. It serves as a critical interface component for converting single-ended signals to differential formats or vice versa. The series is known for consistent performance across wide bandwidths in compact form factors.

Balun Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Verify pin compatibility and electrical parameters if considering alternative baluns. Consult manufacturer engineering support for qualified alternate parts with identical footprint and performance characteristics.
