TCM2-33WX+

Overview

The TCM2-33WX+ is a surface-mount RF balun manufactured by Mini-Circuits, designed for operation within a frequency range of 10 MHz to 3 GHz. It features a 1:2 impedance transformation ratio and utilizes a 6-SMD flat lead package measuring 4.06 mm x 3.81 mm x 4.06 mm. Key electrical specifications include a maximum insertion loss of 3 dB, a minimum return loss of 13.77 dB, and a phase difference of 4 degrees. The component supports a maximum DC current of 30 mA and has a power rating of 400 mW. It operates reliably between -40°C and +85°C and complies with RoHS3 standards.

Feature Summary

• Provides balanced-to-unbalanced signal conversion with a 1:2 impedance ratio
• Supports wideband operation from 10 MHz to 3 GHz
• Compact surface-mount design suitable for automated assembly

Applications

• RF front-end circuits requiring impedance matching
• Balanced mixer local oscillator inputs
• Single-ended to differential signal conversion in wireless modules

Procurement Notes

Verify the specific suffix designation against official Mini-Circuits documentation to ensure correct variant selection. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C limits. Ensure PCB layout guidelines for the 6-SMD flat lead package are followed to maintain electrical performance and mechanical stability during soldering processes.

Selection Notes

Select this component when a compact solution is needed for converting single-ended signals to balanced outputs or vice versa within the VHF/UHF spectrum. Consider the 1:2 ratio for applications requiring specific impedance transformations rather than standard 1:1 configurations. Evaluate the low insertion loss and high return loss requirements to ensure signal integrity is maintained in sensitive RF paths.

Part Context

This device belongs to the TCM2 series of core and wire SMT transformers produced by Mini-Circuits. The series is characterized by its small footprint and consistent performance across a broad frequency range. These components are widely utilized in modern electronic designs where space constraints and high-frequency reliability are critical factors for system integration.

Replacement Considerations

Consult Mini-Circuits official substitution guides for direct equivalents. Verify pin compatibility and electrical parameters before replacing with other balun models.
