Notes:
1) Open Circuit Inductance Test Parameters: 100kHz, 0.25Vrms, 0.0Adc
+/-20% except for LD1-330-R to LD1-331-R and LD2-470-R to LD2-471-R which is +/-10%
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
5) Part number definition: LDx-yyy-R
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
