Core/Reactor Core FL-V Series LRF251515MKCX

  • RoHS
  • High Permeability


This common mode choke coil uses a nanocrystalline alloy with a high permeability (31,000µ) as its core material. Enabling a high inductance with a small volume and few wraps, this product is ideal for applications focused on size and weight reductions.
