Product Description
Product Overview
This series of 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. They are matched to leading transceiver ICs, ensuring compliance with ITU-T G.703 and other relevant standards for pulse waveform, return loss, and balance. Available in various package types including Dual SMT, Single Through Hole, and Dual Through Hole, these transformers offer isolation voltages of 1500 Vrms (with some models offering 3 kVrms reinforced insulation) and are RoHS-6 compliant. They are suitable for EMI reduction when used in conjunction with common mode chokes.
Product Attributes
