TC9-1+

Balun Overview

The TC9-1+ is an RF balun transformer manufactured by Mini-Circuits, designed for surface-mount applications. It operates within a frequency range of 2MHz to 200MHz and provides a 1:9 impedance transformation ratio between unbalanced and balanced ports. The component utilizes a 5-SMD module package and complies with RoHS3 standards. Key electrical specifications include a maximum insertion loss of 3dB, a minimum return loss of 6.08dB, and a phase difference of 1°. It functions reliably across an operating temperature range of -20°C to +85°C.
