Industrial push-pull isolation transformers

29 September 2021 Passive Components

Components in the Bourns Model PAD00x-T764 series are low-profile, small-footprint isolation transformers with a primary inductance of 475 µH, maximum 11 V·µs ET constant, 400 V d.c. continuous operation, low DC resistance of 550-800 mΩ maximum and an operating temperature range of -40°C to 125°C.

Each transformer in the series is ideal for an isolated RS-485/RS-232 power supply. In addition, the isolation transformers are fit for any serial communication including CAN, RS-485, RS-422, RS-232, SPI, I2C and low-powered LAN.

The transformers operate in the push-pull configuration and they work well with many controllers including the Texas Instruments SN6501 and SN6505, the Maxim MAX253 and MAX845, Analog Devices ADM2485 and other equivalent drivers.
