Design control test voltage is critical. Inductance increases with voltage. 1 3 4 5 1 2 3 4 5 1 2 3 4 5 3 Mechanicals 2. A 2:1 nominal inductance swing from no IDC to operating IDC gives improved protection against current discontinuities at light loading. Inductance increases with greater ETOP. Reference values occur at IDC and low flux density. 3. LI2 rating is the ability of the inductor to store energy. 2 Size Code Lead Diameter (in ±.003) F MIN ± .010 5 2.30/58,42 1.11/28,19 0.90/22,85 1.50/38,10 1.00/25,40 0.20/5,08 0.03/0,76 2.30/58,42 3 1 1 Lead Dia.
