Notes

When ordering, please specify screening code: e.g. ML648PTA472MLZ.
Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4263B LCR meter or equivalent.
DCR measured on a Keithley 580 micro-ohmmeter.
SRF measured using an Agilent E5061 network analyzer and impedance option using fixture CCF1592 with mask 297A1751 and shim 297A1765.
DC current at which the inductance drops 10% (typ) from its value without current.
Current that causes the specified temperature rise from 25°C ambient. When Irms is greater than Isat, Isat is the more critical specification, and Irms is shown in gray type. See Temperature Rise vs Current curve below.

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)
1/2/3 = EEE-INST-002 (Family 1) Level 1/2/3
4/5 = MIL-STD-981 (Family 04) Class B=4, Class S=5
F = Screening per ESCC 3201
Screening performed to the document’s latest revision.
Lot qualification (Group B) available.
Testing T and U have been replaced with more detailed codes 4, 5, and 1, 2, 3, respectively. Codes T and U can still be used, if necessary. Custom testing also available.
Country of origin restrictions available; prefix options G or F.
