TC1-1TX+

Balun Overview

The TC1-1TX+ is a surface-mount RF transformer manufactured by Mini-Circuits, designed for balanced-to-unbalanced signal conversion. It operates within a frequency range of 400 kHz to 500 MHz and maintains a 1:1 turns ratio with 50/50 Ohm impedance matching. The component utilizes a 6-SMD (5 Leads) package featuring flat leads, measuring 3.81 mm in length and width with a height of 3.81 mm. It supports a maximum DC current of 30 mA and functions reliably across an operating temperature range of -40°C to +85°C.
