SM91519L and SM91527L BMS Signal Transformers

Bourns Magnetics' single-channel, reinforced insulation transformers include common mode chokes for noise rejection in BMS applications

Image of Bourns SM91519L and SM91527L BMS Signal TransformersBourns Magnetics Product Line's Model SM91519L and SM91527L BMS signal transformers are single-channel, reinforced insulation transformers that include common-mode chokes for noise rejection in BMS applications.

These models work well with the NXP Model MC33771C series and Analog Devices’ Model LTC6804/681X series. These BMS signal transformers offer a working voltage of up to 1500 VDC and a hipot isolation voltage of up to 6400 VDC (SM91519L) and 7640 VDC (SM91527L) with an extended operating temperature range of -40°C to +125°C. The solid design of the SM91527L transformer can help customers pass the partial discharge test per IEC 60664 up to 2250 V and the impulse voltage test up to 12 kV (1.2 / 50 µS.
