NI PXI-5154

Aimed at LAN applications, Epcos has developed magnetic modules for both electrical isolation and suppression of common-mode and differential-mode interference. The modules are available in single, dual and quad-port versions and are qualified to IPC/JEDEC J-STD-020C and IEEE 802.3. The electrical isolation can withstand a breakdown voltage of 1,500 Vac.

The insertion loss of the modules is only -1dB. Values of -16dB and -40dB are attained for return loss and crosstalk, respectively. In addition to the standard temperature range from 0°C to +70°C, versions with an extended temperature range from -40°C to +85—C were developed for industrial applications. Typical applications are 10/100 Base-T, 1000 Base-T as well as PoE (Power over Ethernet).
