1. Open circuit inductance (OCL) test parameters: 100 kHz, 0.25 Vrms, 0.0 Adc, +25 °C
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 @ +25 °C
4. Isat2: Peak current for approximately 40% rolloff @ +125 °C

5. K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * ΔI. Bp-p:(Gauss), K:
(K-factor from table), L: (Inductance in μH), ΔI (Peak-to-peak ripple current in Amps).
6. Part Number Definition: DRAP124-xxx-R
DRAP124= Product code and size
xxx= Inductance value in μH, R= decimal point, If no R is present last character equals number of
zeros
-R suffix = RoHS compliant

All soldering surface to be coplanar within 0.1 millimeters
Tolerances are ±0.2 millimeters unless stated otherwise
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.
Terminal pads shall protrude the plastic base 0.00~0.08 mm
Traces or vias underneath the inductor is not recommended
