When leads are connected in parallel, inductance is the same value. When leads are connected in series, inductance is four times the value. R is for each winding. DC When leads are connected in parallel, R = R x R / R + R . When leads are connected in parallel, DC 1 2 1 2 R is half the value. When leads are connected in series, R is twice the value. I is the current DC DC sat flowing through one winding. When leads are connected in parallel, I is the same. sat When leads are connected in series, I is half the value. I is the total current through both windings. sat R 2 2 2 I and I can be calculated like this: I + I = I 1 2 1 2 R TDK Electronics AG Edition 2020 Ordering No. B82477D4*M900 SO 0520
