Isat is the DC current which cause the inductance drop approximately 20% of its nominal inductance without current. Irms is the DC current which cause the surface temperature of the part increase less than 45OC. Operating temperature : -40OC to 125OC ( including self-temperature rise ). DELTA ELECTRONICS, INC.
