DR124
High power density, high efficiency, low profile shielded drum
core power inductors
Technical Data
4141
Effective March 2019
Product specifications
1. Open Circuit Inductance Test Parameters: 100 kHz, 0.25 V, 0.0 Adc.
2. I
rms: DC current for an approximate ∆T 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 +125 °C under worst case operating conditions verified in the end
application.
3. I
sat Amps peak for approximately 25% rolloff (@ +25 °C).
4. K-factor: Used to determine B
p-p for core loss (see graph).
B
p-p = K*L*∆I, Bp-p (mT), K: (K factor from table), L: (Inductance in μH),
∆I (Peak to peak ripple current in Amps).
5. Part Number Definition: DR124-xxx-R
- DR124 = Product code and size; -xxx = Inductance value in uH;
- R = decimal point; If no R is present, third character = # of zeros.
- “-R” suffix = RoHS compliant
