IC - T3/DS3/E3/STS-1 - Catalogue


These miniature transformers are suitable for 75 ohm bandwidth applications requiring a very fast rise times.



We offer a wide range of transmit and receive transformers for 13/D83 applications using bit rates of 4.736 Mbps. These transformers can also be used with E3 interfaces at 34.368 Mbps and STS-1 applications at 51.84 Mbps.
A listing of IC´s with recommended Talema transformers is listed on the following cross-reference chart.
 
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 of CCITT G.703 and ATT T.A.34 can be met. Additionally all parts are 100% tested for 1,500V minimum isolation.    
  Temperature Performance
Products are offered for both standard temperature (Commercial 0° to +70°C) and extended temperature (Industrial -40° to +85°C) applications. Required minimum inductance levels are maintained at the lower temperature limits.
