AlfaMag Electronics DJE Series T3/DS3/E3/STS-1 Interface Transformers

DJE Series

AlfaMag Electronics DJE Series T3/DS3/E3/STS-1 Interface Transformers

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

Our overseas manufacturing plant produces a wide range of transmit and receive transformers for T3/DS3 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 are listed on our specification sheet/cross reference chart for the DJE Series in our Product Index on our website.

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 Waveshape requirements of CCITT G.703 and ATT T.A.34 can be met. Additionally all parts are 100% tested for 1500V minimum isolation.

Features
* Low cost SMD for pick and place compatability while providing consistent and reliable coplanarity
* Low leakage inductance
* Excellent quality at extremely competitive price due to high volume production
* Manufactured in our ISO-9001 approved facility
