Würth Elektronik’s Oval Ferrite Ring Supress Interference at Low Frequencies

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 MnZn ferrite 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 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. WE-OEFA-LFS is available ex-stock, and free samples are provided for developers.
