TTC-5023

Overview

The Tamura TTC-5023 is a surface mount audio transformer designed for voice and modem applications. It features a 1:1 turns ratio with primary and secondary impedances of 600 ohms each. The device operates within a frequency range of 200Hz to 4kHz, maintaining a frequency response of ±0.25dB. Key electrical specifications include a maximum DC resistance of 115 ohms per winding, an insertion loss of 2dB minimum at 2kHz, and an echo loss of 14dB minimum across the operating band. It provides 3000VRMS isolation for one minute and functions between -20°C and 85°C.
