ST466PJD Series

Coupled Inductors for Critical Applications

The ST466PJD Series coupled miniature shielded inductors are only 3 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.

Notes
  1. When ordering, please specify termination and screening code: e.g. ST466PJD105MLZ.
  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 which the inductance drops the specified amount 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. See temperature rise calculation.
  8. Maximum current when applied to one winding that causes a 40°C temperature rise from 25°C ambient. See temperature rise calculation.

Termination:

  • L =Silver-palladium-platinum-glass frit.
  • R = Matte tin over nickel over silver.
  • T =Tin-silver-copper (95.5/4/0.5).
  • S =Tin-lead (63/37).

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)
All screening performed to the document’s latest revision.
Custom screening also available.
