The LPD5010 coupled miniature shielded inductors are mere 1 mm high and 5 mm square. They are ideal for use in a variety of circuits including flyback, multi-output buck, SEPIC and Zeta. These inductors provide high inductance, high efficiency and excellent current handling in a rugged, low cost part. They can also be used as two single inductors connected in series or parallel or as a common mode choke.
