2 Representative samples of the product were subjected to the conditioning described in IPC/JEDEC J-STD-020D and passed electrical
testing, package coplanarity and visual inspection which revealed no external cracks or changes in package body flatness.
3 I
DC
is the value at which the inductance falls to 80% of its nominal value or when its temperature reaches 40 C, which ever is sooner.
4 I
SAT
is the value at which the inductance falls to 80% of its nominal value.
