TCM1-1X+

Balun Overview

The TCM1-1X+ is a surface-mount RF balun transformer manufactured by Mini-Circuits. It operates within a frequency range of 1.5 MHz to 500 MHz and provides impedance transformation between unbalanced and balanced circuits, both rated at 50 Ohms. The component features a 6-SMD flat lead package with dimensions of 4.06 mm x 3.81 mm x 4.06 mm. Electrical specifications include a maximum insertion loss of 3 dB, a minimum return loss of 7.88 dB, and a phase difference of 4°. It supports a maximum DC current of 30 mA and has a power rating of 250 mW. The device functions reliably across an operating temperature range from -20°C to +85°C.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion for RF applications
• Supports wide bandwidth operation from 1.5 MHz to 500 MHz
• Designed for surface-mount assembly in compact electronic systems

Balun Applications

• RF circuit impedance matching
• Signal transmission line balancing
• Communication equipment interface design

Balun Procurement Notes

Verify the specific suffix designation to ensure correct packaging configuration, as variants exist for cut tape, reel, or Digi-Reel formats. Confirm that the selected version meets the required RoHS3 compliance standards for environmental regulations. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and avoid counterfeit components. Ensure the procurement channel provides valid traceability documentation for quality assurance purposes.

Balun Selection Notes

Select this component when a 50-Ohm to 50-Ohm impedance transformation is required within the 1.5 MHz to 500 MHz frequency band. Evaluate the physical footprint constraints to ensure compatibility with the 6-SMD flat lead package dimensions. Consider the thermal operating limits and power handling capabilities relative to the system's maximum DC current and power rating requirements.

Balun Part Context

This component belongs to the TCM1 series of core and wire transformers produced by Mini-Circuits. The series specializes in surface-mount RF and microwave components designed for high-performance signal processing. These transformers are engineered to provide reliable impedance conversion and signal balancing in compact form factors suitable for modern electronic manufacturing.

Balun Replacement Considerations

Direct substitutes within the same series include the TCM1-1+, which shares identical electrical characteristics but may differ in packaging options. Other models in the TCM1 family offer similar functionality with varying frequency ranges or power ratings.
