MS412PJD Series

Coupled Inductors for Critical Applications

MS412PJD Series coupled inductors for critical applications feature 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.
  • Only 1.4 mm high and 3 mm square.
  • Ideal for use in flyback, multi-output buck, SEPIC and Zeta applications.
  • The tin-lead (Sn-Pb) termination offers the best possible board adhesion.
  • Tin-lead (63/37) over tin over nickel terminations.

Notes
  1. When ordering, please specify screening codes: MS412PJD34MSZ.
  2. Inductance shown for each winding, measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent. When leads are connected in parallel, inductance is the same value. When leads are connected in series, inductance is four times the value.
  3. DCR is for each winding. When leads are connected in parallel, DCR is half the value. When leads are connected in series, DCR is twice the value.
  4. SRF measured using an Agilent/HP 4191A or equivalent. When leads are connected in parallel, SRF is the same value.
  5. Leakage Inductance is for L1 and is measured with L2 shorted.
  6. DC current at 25°C that causes the specified inductance drop from its value without current. It is the sum of the current flowing in both windings.
  7. Equal current when applied to each winding simultaneously that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
  8. Maximum current when applied to one winding that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
