TC1-6+

Balun Overview

The TC1-6+ is a surface-mount RF balun transformer manufactured by Mini-Circuits, designed for broadband applications within the 150 kHz to 350 MHz frequency range. It provides impedance transformation between unbalanced and balanced circuits, both rated at 50 Ohms. The component operates reliably across a temperature span of -40°C to +85°C and supports a maximum DC current of 30 mA with a power rating of 250 mW. Housed in a compact 5-SMD module package measuring 3.81 mm x 3.81 mm x 4.06 mm, it features a phase difference of 2° and a maximum insertion loss of 3 dB. Minimum return loss is specified at 9.26 dB, ensuring efficient signal transfer.
