Würth Elektronik has released the WE-OEFA-LFS , which is an oval-shaped ferrite ring designed 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 MnZn 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 designed for high-current applications and the frequency range from 1 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 × 65.4 × 35.4 mm, while the cable or busbar it encloses can measure 43 × 13 mm.
