LAN 10/100 Base-T Transformers and BMS Signal Transformers
Bourns' LAN 10/100 Base-T transformers and BMS signal transformers provide a variety of options for user needs
Bourns' model SM13100EL and SM91074AL single-port and LAN 10/100 Base-T / isolation transformer modules include common mode chokes for noise rejection in Ethernet applications.
The model SM13100EL is IEC 60601-1 and IEC 60950-1 compliant, UL Recognized, and is suitable for industrial Ethernet, Ethernet home appliances, and other market segments where higher insulation is required. It offers a 4000 VRMS isolation voltage and a 250 VRMS working voltage with an extended operating temperature range of -40°C to +85°C.
The model SM91074AL LAN transformer offers a 1500 VRMS isolation voltage and an extended operating temperature range of -40°C to +125°C.
Bourns BMS signal transformers are model SM91501AL and model SM91502AL. The model SM91501AL is a dual-channel isolation transformer module, and the model SM91502AL is a single-channel isolation transformer module. Both models include common mode chokes for noise rejection for BMS applications and hold reference designs with Analog Device's model LTC6804-1/6811 and NXP's MC33771/ 33772. These models are AEC-Q200 compliant.
The model SM91501AL offers a 1600 VDC working voltage while the model SM91502AL features a 1000 VDC working voltage. Both models provide a 4300 VDC hipot isolation voltage and an extended operating temperature range of -40°C to +125°C.
