Features
Applications
• Special winding technology for
tight coupling of the two windings
(coupling factor K = 950 to 990)
• DC/DC converter,
especially for SEPIC
topology
• Magnetically shielded
• Winding welded to terminals
• Buck converter with
auxililary output
• Common mode
choke
• Base plate construction
for high mechanical robustness
• 1:1 transformer
• Temperature range up to +152 °C
• Qualification to AEC-Q±22
Inductance is per winding. When leads are connected in parallel, inductance is the same value.
When leads are connected in series, inductance is four times the value. RDC is for each winding.
When leads are connected in parallel, RDC = R1 x R2 / R1 + R2. When leads are connected in series,
RDC = R1 + R2. Isat is the current flowing through one winding. When leads are connected in parallel,
Isat is the same. When leads are connected in series, Isat is half the value. IR is the total current through
2
both windings. I1 and I2 can be calculated like this: I12 + I22 = IR
