Notes

When ordering, please specify termination and screening codes: e.g. ST432PNA104MLZ.
Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD-A fixture in an Agilent/HP 4263B LCR meter or equivalent.
SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD -D test fixture.
DC current at which the inductance drops the specified amount from its value without current.
Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.

Termination:

L = Matte tin over nickel over phos bronze.
T = Tin-silver-copper (95.5/4/0.5). (Special order, added cost)
S = Tin-lead (63/37). (Special order, added cost)

Note: These inductors have internal parts that contain 100% tin.

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.
