EMI suppression in the low-frequency range directly on the busbar

24 October 2024

With the WE-OEFA-LFS ferrite, Würth Elektronik is releasing an oval-shaped ferrite ring for interference suppression at low frequencies. Thanks to its unique oval shape, the ferrite ring is particularly easy to slide over busbars for interference suppression. Its manganese-zinc core material makes it perfect for suppressing low-frequency interference. The main application area for the new ferrite is electric vehicles.

The AEC-Q200-certified WE-OEFA-LFS, with an operating temperature range of -40° C to 105° C, is designedSource: Würth ElektronikSource: Würth Elektronik for high-current applications and the frequency range from 1 MHz to 100 MHz. This enables the ferrite to suppress electromagnetic interference in battery management systems, inverters, on-board chargers, cable harnesses and many other applications.

The latest interference suppression ferrite in Würth Elektronik's portfolio measures 15.6 mm × 65.4 mm × 35.4 mm, while the cable or busbar it encloses can measure 43 mm × 13 mm. WE-OEFA-LFS is available ex-stock, and free samples are provided for developers.
