EPCOS have developed RJ45 LAN jacks with integrated magnetic modules for the electrical isolation of common and differential-mode interference. The RJ45 LAN jacks are available from Ramelec Electronics in single, dual and quad-port versions and correspond to IEEE 802.3. The housing design satisfies UL 94 V-0 and TIA-968.
The electrical isolation can withstand a breakdown voltage of 1500V AC. The modules have an insertion loss of -1.0dB. Values of -16dB and -40dB are attained for the reflection loss and crosstalk respectively. The components are designed for a temperature range from 0°C to +70°C. Two integrated LEDs display the status of the network connection. Applications include hubs, routers, DSL modems as well as industrial automation equipment, PCs and laptops. The jacks are suitable for 10/100 Base-T, 1000 Base-T, and PoE (Power over Ethernet).
