Bourns SM91519L and SM91527L series BMS signal transformers
Bourns announces SM91519L and SM91527L series BMS (Battery Management System) signal transformers
Bourns Magnetics offers the model SM91519L and SM91527L BMS signal transformers. These single channel, reinforced insulation transformers include common mode chokes for noise rejection in BMS applications.
These models work well with the NXP Model MC33771C series and Analog Device’s model LTC6804/681X series. These BMS signal transformers offer a working voltage of up to 1,500VDC and a hi-pot isolation voltage of up to 6,400VDC (SM91519L) and 7,640VDC (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 2,250V and the impulse voltage test up to 12kV (1.2μS/50μS).
