The PE-65848 and PE-65948 transformers are designed specifically for use with Echelon’s NEURON® 3120TM and NEURON® 3150TM 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 1500 Vrms high voltage isolation for one minute, but are not intended for use as a hazardous voltage safety barrier. Order PE-65848T for optional tape and reel packaging (250 pieces per reel). When using PE-65948, centertaps can be created by connecting winding ends together on the PCB.
