TCM1-1+

Balun Overview

The TCM1-1+ is a surface-mount RF transformer from Mini-Circuits, designed for impedance matching and signal transformation in the 1.5 MHz to 500 MHz frequency range. It features a single-channel configuration with 50 Ohm primary and secondary impedances. The component operates within a temperature range of -20°C to +85°C and supports a maximum DC current of 30 mA with a power rating of 250 mW. Housed in a compact DB714 package measuring 4.06 mm x 3.81 mm x 4.06 mm, it utilizes SMD/SMT termination for automated assembly.
