Bourns Releases Industrial Push-Pull Isolation Transformer
Model PAD00x-T764 Series
Riverside, California – September 15, 2021 – The Bourns Custom Magnetics Product Line is introducing the new
Model PAD00x-T764 Push-Pull Isolation Transformer Series. The Model PAD00x-T764 series are low profile,
small footprint isolation transformers, with a primary inductance of 475 µH, maximum 11 V-μS, 400 VDC
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 ideal for any serial communication including CAN, RS-485, RS-422, RS-232, SPI, I
2
C and
low powered LAN. The transformers operate in the push-pull configuration and they work well with many
controllers including the TI SN6501 and SN6505, the Maxim MAX253 and MAX845, Analog Devices ADM2485
and other equivalent drivers. These models are ideal for use in various applications, including industrial
automation, AC motor drives, smart metering, solar inverters, and more.
The Model PAD00x-T764 Series Push-Pull Isolation Transformers are designed for a 400 VDC continuous
working voltage and comply with IEC 62368. They are RoHS* and REACH compliant.
