Notes

When ordering, please specify screening code: e.g. ML420PJB105MLZ.
Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4192A.
DCR measured on a micro-ohmmeter.
SRF measured using an Agilent/HP 8753ES or equivalent.
DC current at 25°C that causes the specified inductance drop 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.

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)
Screening performed to the document’s latest revision.
Custom testing also available.
Country of origin restrictions available; prefix options G or F.
