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
