Notes
  1. When ordering, please specify termination and screening codes: e.g. MS512PJD105MSZ.
  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. Equal current when applied to each winding simultaneously that causes a 40°C temperature rise from 25°C ambient. Calculate temperature rise.
  7. 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:

  • Z = Unscreened
  • Y = Unscreened (SLDC Option A)
  • W = Unscreened (SLDC Option B)
  • H = Group A screening per Coilcraft CP-SA-10001
  • G = Coilcraft CP-SA-10001 Group A (SLDC Option A)
  • D = Coilcraft CP-SA-10001 Group A (SLDC Option B)
  • N = Group A screening per Coilcraft CP-SA-10004
