1 Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.25Vrms, 0.0Adc, @ +20°C.
2 Full Load Inductance (FLL) Test Parameters: 100kHz, 0.25Vrms, Isat @ +20°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 20% rolloff at +20°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: HCM0703-xxx-R
• HCM0703 = Product code and size
• xxx= Inductance value in μH, R = decimal point,
If no R is present then 3rd digit equals number of zeros.
• “-R” suffix = RoHS compliant
