SMD Device

1 Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.10Vrms, 0.0Adc

2 Full Load Inductance (FLL) Test Parameters: 100kHz, 0.1Vrms,Isat1

3Irms: DC current for an approximate temperature rise of 40°C without core loss. Derating is

necessary for AC currents. PCB pad layout, trace thickness and width, air-flow and proximity of

other heat generating components will affect the temperature rise. It is recommended the part

temperature not exceed 155°C under worst case operating conditions verified in the end

application.

4Isat: 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 : (Gauss), K: (K-factor

from table), L: (inductance in

μH), ΔI (peak-to-peak ripple current in amps).

6 Part Number Definition: HCP0704-xxx-R

• HCP0704 = Product code and size

• xxx= Inductance value in

μH, R = decimal point. If no “R” is present, then

third character = # of zeros

• “-R” suffix = RoHS compliant
