1. Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.25Vrms, 0.0Adc
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
