Bourns HCTSM151207FAL series

Bourns inductive components product line is introducing the model HCTSM151207FAL high clearance/creepage distance isolation power transformer. This new transformer is AEC-Q200 compliant and automotive grade. The high voltage isolation transformer is driven by 24V input and delivers 12V, up to 100mA output, and can be configured in a variety of turns ratios if needed.

The transformer is designed to support isolated interface power for CAN, RS-485, RS-422, RS-232, SPI, I2C and lower power LANs in a range of applications such as Industry 4.0 and any application that requires isolation from potentially hazardous voltages (e.g., from a high voltage battery especially inside 1500V energy storage systems).

The model HCTSM151207FAL is built with a ferrite toroid core for high coupling factor and efficiency. It offers a working voltage of up to 1500VDC with an operating temperature range from -40°C to +125°C. The reinforced isolation, 15mm min. clearance/creepage distance, and 7.64kV at 2seconds withstanding voltage provide an elevated degree of isolation from high voltage hazards. The transformer is designed for isolation power supplies using Texas Instruments’ SN6501 and SN6505B, and are compliant with IEC 60664-1/UL 62368-1and IEC 62368-1 standards.
