High Current Air Core Inductors Coilcraft High Current Air Core Inductors handle up to 57A with no core loss, and the size of these inductors results in excellent Q factors, up to 230 at 400MHz. These devices offer inductance values ranging from 22nH to 257nH, all with ±20% tolerance. High-reliability versions are available for RF, space, military, and other critical applications. Coilcraft High Current Air Core Inductors feature dimensions of 10mm x 10mm x 3.6mm and are RoHS and REACH compliant.
