1) Open Circuit Inductance Test Parameters: 100kHz, 0.25 V , 0.0 Adc

rms

6) Turns Ratio (1:3):(2-4) 1:1

Parallel: (1,2 -4,3) Series: (1-4) tie (2-3)

7) Part number definition: DRQxxx-yyy-R

DRQxxx = product code and size,

-yyy = inductance value in µH,

2) RMS current for an approximate ∆T of 40°C without core loss. It is recommended that the

temperature of the part not exceed 125°C.

3) Peak current for approximately 30% roll-off at 20°C

4) DCR limits @ 20°C

R = decimal point. If no R is present, third character = # of zeros

-R suffix = RoHS compliant

5) Applied Volt-Time product (V-µS) across the inductor. This value represents the applied V-µS

at 100KHz necessary to generate a core loss equal to 10% of the total losses for a 40°C

temperature rise.
