Würth Elektronik New Products Summer 2022

Würth Elektronik introduces its Summer 2022 new products in the areas of power inductors, power battery management transformers, RF components and signal transformers, optoelectronics, as well as MagI³C power modules.

A transformer for battery management systems and a UV-A LED are just a couple of highlights.

A brochure with information on the additions to the portfolio is provided by the technology enabler for free download.

SMT power inductor WE-XHMI


SMT power inductor with flat power and composite core allows high saturation current in compact case. The design is optimized for high ripple current capability and transient current spikes ideal for DC/DC power converters in wide range of applications.


  • Flat wire coil for low copper losses
  • Composite core material allows high saturation currents
  • Compact design
  • Magnetically shielded
  • High current capability and handles high transient current spikes
  • Low leakage flux noise
  • Operating temperature: -40°C up to +125°C


  • DC/DC-converter for high current power supplies
  • DC/DC-converter for Field Programmable Gate Array (FPGA)
  • Power supplies for mobile devices
  • POL-converters
  • Mainboards / graphic cards
  • Battery powered devices
  • Wireless communication devices
  • Filter
Transformer for battery management systems WE-BMS


The new product series include the WE-BMS transformer for battery management systems—ideal for use in energy storage systems, e-bikes or e-scooters thanks to its galvanic isolation of 4300 VDC / 1 min, high operating voltage of up to 1000 VDC and integrated filter chokes.


  • Supports high isolation for BMS systems
  • Supports serial daisy chain isoSPI and SPI
  • 1000 VDC working voltage
  • Isolation test voltage 4300 VDC
  • AEC-Q200 qualification
  • Strong EMI reduction
  • Available in different footprints
  • Low profile versions available
  • Operating temperature: -40°C up to +125°C


  • Solar energy storage systems
  • Energy storage systems
  • Uninterrupted power supply (UPS)
  • E-bikes, E-scooters

The additions also include new MagI³C power modules, new sizes in the WE-XHMI storage choke series, plus the WE-MCA multilayer chip antennas, for which Würth Elektronik also offers an antenna matching and characterization service.


Würth Elektronik’s Optoelectronics business unit was not idle either: A UV-A LED with a flat PLCC2 standard package is introduced—WL-SUTW—which can be used in UV curing lamps or for sensing applications. Also new—the UV-C LEDs in the WL-SUMW series for sterilization applications.

The range of seven-segment displays has also grown: Würth Elektronik now has the WL-S7DS and WL-T7DS models of the robust display modules in SMT and THT versions in its product range.

All components presented in the new product catalogue are now available from stock. Würth Elektronik provides customers with samples from the entire range, free of charge for prototyping.
