SMD Device
1. Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.25Vrms, 0.0Adc @ 25°C.
2. Full Load Inductance (FLL) Test Parameters: 100kHz, 0.25Vrms,I
sat @ 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 approx. 20% rolloff at +25°C - HCM1104-R20-R to HCM1104-R90-R.
5. Isat: Peak current for approx. 30% rolloff at +25°C - HCM1104-1R0-R to HCM 1104-100-R.
6. 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).
7. Part Number Definition: HCM1104-xxx-R
- HCM1104 = Product code and size
- xxx= Inductance value in μH, R = decimal point
- “-R” suffix = RoHS compliant
