1. Open Circuit Inductance (OCL) Test Parameters: 100 kHz, 0.25 Vrms, 0.0
Adc
2. Irms: DC current for an approximate temperature rise of 40 °C without core
loss. Derating is necessary for AC currents. PCB layout, trace thickness and
width, air-flow and proximity of other heat generating components will affect
the temperature rise. It is recommended that the temperature of the part not
exceed +165 °C under worst case operating conditions verified in the end
application.
3. Isat1: Peak current for approximately 30% rolloff at +25 °C.
4. Isat2: Peak current for approximately 40% rolloff at +125 °C.
5. K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * I.
Bp-p:(Gauss), K: (K-factor from table), L: (Inductance in µH), I (Peak-to-peak
ripple current in Amps).
6. Part Number Definition: DRAQxxx-xxx-R
- DRAQxxx = Product code and size
- xxx= Inductance value in uH, R = decimal point, If no R is present then 3rd
digit equals number of zeros.
- “-R” suffix = RoHS compliant
Dimensions - mm

R = revision level
All soldering surfaces to be coplanar within 0.10 millimeters
Tolerances are ± 0.2 millimeters unless stated otherwise.
Do not route traces or vias underneath the inductor
*Special Characteristic epoxy protrusion or any flashing from the plastic on the header/base can be below the terminal surface and must not exceed 0.08
mm beyond the bottom surface of the terminal.
