(2) RMS current is the approximate current at which inductance will decrease by 10% from its initial value (zero DC) or the DC current at which ∆T = 40°C, whichever is lower. (3) Saturation current for approximately 30% roll-off.

Frequently Asked Questions
What is the maximum operating temperature range?
The components have an operating temperature range of -40°C to +125°C, with a maximum ambient temperature of 85°C.
How are the different listed current ratings measured?
Saturation current is calculated for approximately 30% roll-off. RMS current is defined as the approximate current where inductance will decrease by 10%.
What does the model code indicate about the rated inductance value?
In the inductor code, the first two digits are significant, and the last digit denotes the number of trailing zeros.
