1. Open Circuit Inductance (OCL) Test Parameters: 100 kHz, 0.25 Vrms, 0.0 Adc @
+25 °C
2. Full Load Inductance (FLL) Test Parameters: 100 kHz, 0.25 Vrms, Isat @ +25 °C.
3. 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 +125 °C under worst case operating conditions verified in the end
application.
4. Isat: Peak current for approximately 30% rolloff at +25 °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: HCM1103-xxx-R
HCM1103 = Product code and size
xxx= Inductance value in µH, R = decimal point,
if no R is present then third character = number of zeros.
-R suffix = RoHS compliant
