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.
