TCM2-1T+

Balun Overview

The TCM2-1T+ is a surface-mount RF balun transformer from Mini-Circuits, designed for balanced-to-unbalanced signal conversion. It operates within a frequency range of 3 MHz to 300 MHz and features a 1:2 impedance ratio with 50 Ohm primary and secondary impedances. The component supports a maximum DC current of 30 mA and has a power rating of 250 mW. It functions as a single-channel device housed in a compact SMD package measuring 3.81 mm x 3.81 mm x 4.06 mm. The unit is rated for operation between -40°C and +85°C.

Balun Feature Summary

• Provides balanced-to-unbalanced (balun) signal transformation
• Supports wideband operation from 3 MHz to 300 MHz
• Utilizes surface-mount technology for automated assembly

Balun Applications

• RF circuit design requiring impedance matching
• Telecommunications signal processing

Balun Procurement Notes

Verify the specific datasheet version ED-7875/8 or later when sourcing this component. Confirm that the ordering suffix '+' indicates RoHS compliance. Ensure the procurement channel provides official Mini-Circuits documentation to validate the electrical specifications against the 3 MHz to 300 MHz operational range. Cross-reference the package dimensions for PCB layout accuracy.

Balun Selection Notes

Select the TCM2-1T+ when a 1:2 ratio balun is required for frequencies up to 300 MHz. This component is suitable for applications needing 50 Ohm impedance matching on both sides. Consider the surface-mount footprint and thermal operating range of -40°C to +85°C during board design. Verify that the 30 mA DC current limit meets the circuit requirements.

Balun Part Context

This part belongs to the TC2 series of audio and signal transformers manufactured by Mini-Circuits. The series includes various transformer configurations optimized for RF and microwave applications. The TCM2-1T+ specifically addresses the need for compact, high-performance balun solutions in modern electronic designs where space constraints are critical.
