WE-BMS SMT Transformers for Battery Management Systems
Würth Elektronik’s WE-BMS transformers meet the requirements for high-voltage operation areas creating a safe and reliable BMS
Würth Elektronik’s WE-BMS transformers contain a common mode choke to filter common mode noise and electrically isolate the signals, allowing them to support the battery management systems (BMS) isolation and EMI noise suppression for a safe and reliable operation. These transformers feature a low profile design and provide a higher creepage distance than other BMS. The higher creepage distance increases the safety and reliability of the system despite the footprint.
Features
- Galvanic isolation of 4300 VDC/1 minute
- Low profile versions
- AEC-Q200 qualification
- Supports serial daisy chain isoSPI and SPI
- Up to 1000 VDC working voltage
- Integrated filter chokes for common mode suppression
- Available in different footprints
- Operating temperature: -40°C to +125°C
Applications
- Energy storage systems (ESS)
- Solar energy storage
- Uninterrupted power supplies (UPS)
- E-mobility:
- E-bikes
- E-scooters
