Bourns SM91502ALA series AEC-Q200 compliant BMS signal transformer

Bourns is introducing the model SM91502ALA AEC-Q200 compliant BMS signal transformer. This single channel functional insulation transformer includes common mode chokes for noise rejection in BMS applications.

The model SM91502ALA was developed for use with Analog Device’s LTC6804-1/681X, NXP’s MC33771/33772 and Texas Instruments’ BQ79616. This new model utilizes a higher level of automation in the pin winding process to enhance product quality and production efficiency. This BMS transformer offers a working voltage of up to 1000VDC and a Hi-PoT isolation voltage up to 4300VDC with an extended operating temperature range of -40°C to +125°C.
