RIVERSIDE, Calif., February 28, 2024 - Bourns, Inc., a leading manufacturer and supplier of electronic components for power, protection, and sensing solutions, today introduced a new single channel basic insulation transformer with a planar structure optimized for Battery Management System (BMS) applications. Bourns® Model SM91801AL is the next ‘first to market’ BMS signal planar transformer product Bourns has engineered, and is developed for use with several prominent semiconductor supplier IC series: Analog Device Model LTC6815 Series, NXP Model MC33771C Series and Texas Instruments Model BQ79616 ICs that are primarily used in multi-cell battery monitoring designs.

The latest BMS planar signal transformer from Bourns is AEC-Q200 compliant and automotive grade. It features a basic insulation layer that complies with IEC 60664-1 and IEC 62368-1 standards, and is manufactured using a fully automated process to deliver a high quality and cost-effective solution for next-generation applications. This BMS transformer offers a working voltage of up to 1000 VDC and a Hi-Pot isolation voltage up to 4300 VDC or 2500 VAC with an extended operating temperature range of -40 to +125 °C.

Bourns® Model SM91801AL is available now and is RoHS* compliant and halogen free**. For more detailed product information, please see: www.bourns.com/products/magnetic-products/transformers-bms-aecq200.
