Automotive Grade BMS Signal Transformer SM91808AL

Bourns transformers have a planar structure for BMS applications

Image of Bourns Automotive Grade BMS Signal Transformer – SM91808ALBourns low-profile BMS transformer is under 3.5 mm in height above the PCB due to its no-base design structure. The SM91808AL was developed for use with the Analog Devices LTC6815 series, the NXP MC33771C series, and the Texas Instruments BQ79616 series. The transformer offers a working voltage of up to 1,000 VDC and a Hi-Pot isolation voltage of up to 4,300 VDC with an extended operating temperature range from -40°C to +125°C.
