WE-AEFA & WE-AENA Axial EMI Suppression Ferrites

Würth Elektronik WE-AEFA and WE-AENA Axial EMI Suppression Ferrites are AEC-Q200 qualified and work in wide frequency and temperature ranges. They have an operating temperature of -55°C to +150°C with a high process capability that allows for increased automation. The WE-AEFA series utilizes a NiZn core material while the WE-AENA ferrites have a nanocrystaline core material. Würth WE-AEFA and WE-AENA Axial EMI Suppression Ferrites are ideal for wires, coax cables, wire-wrapping cables, multi-conductor wires, data/signal lines, on-board power supply lines, and more.
