AEC-Q200 High Clearance / Creepage Distance Isolation Power Transformers

Bourns, Inc. has introduced its new high clearance/creepage distance isolation power transformer series. Bourns® Model HCT series high-voltage isolation push-pull transformers are AEC-Q200 compliant. Bourns designed its latest transformer series to support isolated interface power for CAN, RS-485, RS-422, RS-232, SPI, I2C, and lower-power LAN.

Solutions that simplify isolated interface power are required in a broad range of applications including those designed to meet Industry 4.0 and in low/medium risk medical sensors, communication PHYs and metering.

The capabilities of the Bourns® Model HCT series are also well-suited solutions for circuits requiring low dc power and any application where isolation from potentially hazardous voltages are needed such as from a high-voltage battery.

The Bourns® Model HCT series features an input range of 3.3- to 5-V and delivers 3.3- to 15-V and up to 350mA output, configured in a variety of turns ratios. The new series is constructed with a ferrite toroid core for high coupling factor and efficiency.

Furthermore, the new power transformers are offered in a low-profile 6.5mm housing with reinforced insulation, at least 8 mm clearance / creepage distance and 4.2kVac withstanding voltage to provide an elevated degree of isolation from high voltage hazards.

Designed for isolation power supplies using Texas Instruments SN6501 and SN6505B transformer drivers, HCT series transformers are compatible with spread spectrum modulation for reduced emissions, and are compliant with IEC 60950-1, IEC 62368-1, IEC 60664-1 and AEC-Q200 standards.

Available now, the Bourns® HCT high-voltage power transformer series is RoHS compliant.
