Product Description
T1/CEPT/ISDN-PRI Transformers
Product Overview
Pulse Electronics T1/CEPT/ISDN-PRI Transformers are designed for use in 1.544 Mbps (T1), 2.048 Mbps (CEPT), and ISDN Primary Rate (PRI) interface applications. These transformers are matched to leading transceiver ICs and are available in various package types including Dual SMT, Single Through Hole, and Dual Through Hole. They are engineered to ensure compliance with ITU-T G.703 and other relevant standards for pulse waveform, return loss, and balance. The product line offers models with extended and standard temperature ranges, and features isolation voltages of 1500 Vrms (with some models offering 3 kVrms reinforced insulation).
