SM91803AL-E AEC-Q200 BMS Signal Transformers

Bourns Model SM91803AL-E AEC-Q200-Qualified Battery Management System (BMS) Signal Transformers are automotive-grade signal transformers for next-generation applications. This Bourns single-channel basic insulation transformer is designed with a planar structure for BMS applications. SM91803AL-E BMS Signal Transformers offer a working voltage of up to 1000VDC and a Hi-Pot isolation voltage of up to 4300VDC or 2500VAC with an extended operating temperature range of -40°C to +125°C.

BMS AEC-Q200-Compliant Signal Transformers

Bourns BMS AEC-Q200-Compliant Signal Transformers offer a protection solution for isolated communications in industrial and consumer battery management systems (BMS). These surface-mount, single- or dual-channel devices monitor essential safety factors such as temperature, state of charge, and device health. Other features include high working voltages of 1000V or 1600V, inductance values in the 150µH to 600µH range, and operating temperatures of up to +150°C. The transformer windings use fully insulated wire passing the hi-pot (dielectric strength) test, which increases electrical insulation protection for overvoltage transients. Bourns BMS AEC-Q200-Compliant Signal Transformers also support serial daisy chain/IsoSPI.

Magnetic Products

Bourns Magnetic Products are engineered to meet essential power application requirements for power conversion, isolation, EMC compliance, signal integrity, and increased power density. Bourns offers a broad, proven, and continually expanding portfolio of miniaturized, automotive grade, high quality, and high-reliability components. Bourns Magnetic Products are key elements in many of today’s breakthrough designs, such as electric vehicles, high power battery charging, e-mobility, renewable energy, energy storage, the Internet of Things (IoT), and industrial infrastructure.
