“Industrial communications interfaces provide isolation to protect peripheral devices from the hazardous voltages created by noisy environments,” said Gerard Healy, product manager, Pulse Electronics Power Business Unit, in a company release. “The PH9085 series uses fully insulated wire to deliver a safe voltage to transceiver circuitry, providing 2500Vrms isolation to the user/operator. These transformers are compatible with various push-pull driver ICs, such as Maxim MAX253, Texas SN6501 and UCC2808, and Analog ADuM4070 and ADuM447x.”
Pulse Electronics’ PH9085 is a push-pull transformer that comes in an industry standard platform as a compact, surface mount package of 8x7x5mm. It provides a direct cross to the Wurth 760 390, Halo TGM-2xNSLF, and Murata 78 253 series of isolation transformers. The transformers are RoHS6 compliant and meet standard EIA481 requirements.
