HCTSM110103HAL HCT Transformer Bourns HCTSM110103HAL HCT Transformer is an AEC-Q200 compliant automotive grade, high-voltage, and high clearance/creepage distance isolation power transformer. This transformer is driven by 3.3V to 5V input, delivers 3.3V to 15V up to 350mA output, and can be configured in various turn ratios when required. The HCTSM110103HAL transformer features a toroid core for a high coupling factor and low radiation and reinforced insulation for working voltage up to 1200VDC. This fully sealed and compact-size transformer supports isolated interface power for CAN, RS-485, RS-422, RS-232, SPI, I²C, and lower-power LANs. This helps in a range of applications, such as Industry 4.0 or any application that requires isolation from potentially hazardous voltages.
