Tolerance of +30% / -20% Request detailed data sheets for specific test conditions. 2) Current which will produce the specified percentage reduction in Inductance. 3) Maximum DC current. This value is for a 40OC temperature rise due to copper loss. Bare Coil Size Chart Size Code 10 11 12 13 14 Where IMAX is greater than IDC @90%, the Inductors can be used for Swing Requirements producing a minimum Swing of 10:1. Where IMAX is greater than IDC @95%, the Inductors can be used for Swing Requirements producing a minimum Swing of 20:1.
