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,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 20% rolloff at +25°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: HCM1305-xxx-R

- HCM1305 = Product code and size

- xxx= Inductance value in

μH, R = decimal point

- “-R” suffix = RoHS compliant
