SMD Device

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.

3Irms: 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.

4Isat: 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 3

• “-R” suffix = RoHS compliant
