MS512PJD Series
Coupled Inductors for Critical Applications
MS512PJD Series coupled inductors for critical applications offer a low profile, only 3.5 mm high and 6 mm square. High inductance, high efficiency and excellent current handling.
- Tight coupling (k ≥ 0.97) makes the MS512PJD series of coupled inductors ideal for use in flyback, multi-output buck and SEPIC applications.
- Tin-lead (Sn-Pb) termination offers the best possible board adhesion.
- Can also be used as two single inductors connected in series or parallel or as a common mode choke.
- Tin-lead (63/37) over tin over nickel terminations.

Notes
- When ordering, please specify termination and screening codes: e.g. MS512PJD105MSZ.
- 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.
- 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.
- SRF measured using an Agilent/HP 4191A or equivalent. When leads are connected in parallel, SRF is the same value.
- Leakage inductance is for L1 and is measured with L2 shorted.
- Equal current when applied to each winding simultaneously that causes a 40°C temperature rise from 25°C ambient. Calculate temperature rise.
- 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. Calculate temperature rise.
Termination:
- S = Non-RoHS tin-lead (63/37).
- R = Matte tin over nickel over silver.
Screening:

- D = Coilcraft CP-SA-10001 Group A (SLDC Option B)
- N = Group A screening per Coilcraft CP-SA-10004
