Lon[®] technology makes possible a new generation of smart, low-cost products that communicate with one another and that can be linked together to serve applications in consumer electronics, factory automation, vehicle controls, commercial building controls, home automation, and other industries. The PE-65848 and PE-65948 transformers are designed specifically for use with Echelon’s Neuron[®] 3120[TM] and Neuron[®] 3150[TM] chips in 1.25 Mbps, twisted pair bus applications. The transformers provide DC isolation 

and common mode noise rejection. Their characteristics have been optimized to assure the proper pulse waveform is transmitted onto the twisted pair cable when used in conjunction with the recommended circuitry. The transformers provide 1500Vrms high voltage isolation for one minute, but are not intended for use as a hazardous voltage safety barrier. Order PE-65848T for optional Tape & Reel packaging. When using PE-65948, center taps can be created by connecting winding ends together on the PCB.
