ISDN S - Standard Signal Transformer Modules


IC - So Interface Module Selection Guide

We provide a wide range of signal transformers for all SO ISDN applications. Space saving modules, available in through hole and surface mount packages, offer a cost effective alternative to individual transformers and chokes and are compatible with all common IC´s. A complete listing of transceiver IC´s with recommended Talema transformer modules is listed on the cross-reference chart below.

Performance has been proven in the many designs of our products in these applications. Quality and consistency is guaranteed through 100% testing of the specified parameters for Primary Inductance, Leakage Inductance, Turns Ratio, DC resistance and Interwinding Capacitance. This ensures that the Return Loss and Pulse Wave shape requirements for S-Interface can be met. Additionally, all parts are tested for 1500V minimum isolation.


Standard Packaging: SMD styles - Tape and Reel; TH styles - Anti Static tubes.		   ISDN S - Standard Signal Transformer Modules
