Shielded Coupled Inductors
LPD4012
• Only 1.1 mm high and 4 mm square
• Ideal for use in flyback, multi-output buck and SEPIC
applications.
• High inductance, high efficiency and excellent current handling
• Can also be used as two single inductors connected in
series or parallel or as a common mode choke.
