Product Description
Product Overview
Pulse Electronics T1/E1/CEPT/ISDN-PRI Transformers are designed for quad port T1/E1 applications, featuring 8 transformers with 1500 Vrms isolation. These transformers are matched to leading quad and dual T1/E1/CEPT/ISDN-PRI transceivers, offering excellent crosstalk attenuation of -65 dB or better. They are RoHS compliant and UL1950 recognized (some parts pending approval), making them suitable for various telecommunications interfaces requiring compliance with standards like ITU-T G.703. The product line also includes high-frequency common mode chokes for EMI compliance.
