1 Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.25V, 0.0Adc

2 Irms: DC current for an approximate Δ T 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 the part

temperature not exceed 125°C under worst case operating conditions verified in the end

application.

3 Isat: Amps for approximately 20% rolloff (@25°C).

4 K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * Δ I, Bp-p: (Gauss), K:

(K-factor from table), L: (inductance in μ H), Δ I (peak-to-peak ripple current in amps).

5 Part Number Definition: HCP1305-xxx-R

? HCP1305 = Product code and size

? xxx= Inductance value in μ H, R = decimal point. If no “R” is present, then

third character = # of zeros

? “-R” suffix = RoHS compliant
