Bourns HCTSM100304FL Isolation Power Transformer features low-profile housing (7.5mm) with 10mm minimum clearance/creepage distance. This high-voltage isolation transformer is built with a ferrite toroid core for a high coupling factor and efficiency. It offers reinforced isolation, 4.2kV (60s) withstanding voltage, and an elevated degree of isolation from high-voltage hazards. The HCTSM100304FL is driven by a 3.3V to 5V input and delivers 3.3V to 15V up to 350mA output. It can be configured in a variety of turn ratios if needed. This transformer is RoHS compliant, complies with IEC 60950-1 and IEC 62368-1 standards, and operates in a -40°C to +125°C temperature range (temperature rise included). Applications for Bourns HCTSM100304FL Isolation Power Transformer include Industry 4.0, RS-485, CAN interface digital input modules, RS-232 isolation, and more.
