The TTC-272N is a low-profile telecommunication dry coupling transformer featuring rigid square pins for secure mounting. It is designed for matching a 600 Ohm primary source impedance to a 600 Ohm secondary load impedance, operating over a level range of -45 dBm to +7 dBm with zero DC. Key electrical characteristics include a typical insertion loss of 1.0 dB at 1 KHz, a flat frequency response of ±0.5 dB from 300 Hz to 3.5 KHz, and a minimum return loss of 26 dB. This transformer provides a dielectric strength of 1500 Vrms between windings and the core, ensuring robust isolation. Its compact, low-profile design makes it ideal for signal coupling in space-constrained telecommunication circuits.
