2) RMS current for an approximate
∆T of 40°C. It is recommended that the temperature of the
part not exceed 125°C
3) Peak current for an approximate 10% rolloff at 20°C
4) DCR limits @ 20°C

LDx = product code and size, -yyy = inductance value in µH,
R = decimal point. If no R is present, third character = # of zeros
-R suffix = RoHS compliant
Description
