Model SM91806AL
Riverside, California – January 9, 2024 – Bourns Magnetics Product Line is pleased to introduce the Model SM91806AL AEC-Q200 compliant, Automotive Grade BMS (Battery Management System) Signal Transformer for next generation applications. This single-channel basic insulation transformer has a planar structure and is designed for BMS applications.
The Bourns® Model SM91806AL BMS Planar Transformer was developed for use with Analog Device’s Model LTC6815 Series, NXP’s Model MC33771C Series and Texas Instruments’ Model BQ79616. This BMS transformer offers a working voltage of up to 1000 VDC and Hi-Pot isolation voltage up to 4300 VDC or 3000 VAC with an extended operating temperature range of -40 to +125 °C. Additionally, Bourns’ automated manufacturing process has further improved the quality and cost-effectiveness of this transformer.
