TCM4-6T+

Balun Overview

The TCM4-6T+ is a 1:4 core and wire RF transformer manufactured by Mini-Circuits. It operates within a frequency range of 1.5 MHz to 600 MHz. The device features a single channel with primary and secondary coil impedances of 50 Ohms each. It supports a maximum DC current of 30 mA and has a power rating of 250 mW. The component is housed in a surface-mount package measuring 4.06 mm x 3.81 mm x 4.06 mm. It functions as an audio and signal transformer suitable for SMD/SMT termination.

Balun Feature Summary

• Provides 1:4 impedance transformation ratio for RF signal processing
• Operates across a wide frequency band from 1.5 MHz to 600 MHz
• Utilizes core and wire construction for high precision parameter measurement

Balun Applications

• CATV systems
• VHF receivers
• VHF transmitters

Balun Procurement Notes

Verify the specific ordering suffix and RoHS compliance status against the manufacturer's latest documentation. Confirm that the surface-mount footprint dimensions match the PCB design requirements. Ensure the operating temperature range of -20 C to +85 C aligns with the system environment. Validate the 50 Ohm impedance matching for both primary and secondary sides before integration.

Balun Selection Notes

Select this component when a 1:4 transformation ratio is required within the 1.5 MHz to 600 MHz spectrum. Consider the 250 mW power rating and 30 mA DC current limit for circuit design. The compact 4.06 mm x 3.81 mm x 4.06 mm package is suitable for space-constrained surface-mount applications. Verify compatibility with VHF receiver and transmitter architectures.

Balun Part Context

The TCM4-6T+ belongs to the TCM4 series of audio and signal transformers produced by Mini-Circuits. This series focuses on RF, IF, and microwave components designed for high reliability.
