1. Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.1Vrms, 0.0Adc @ +25°C

2. Full Load Inductance (FLL) Test Parameters: 100kHz, 0.10Vrms, @ Isat, @ +25°C

3. I

sary 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. I

5. K-factor: Used to determine B p-p for core loss (see graph). B p-p = K*L*∆I, B p-p:(Gauss),

K: (K factor from table), L: (Inductance in μH), ∆I (Peak to peak ripple current in Amps).

6. Part number definition: HCP0805-xxx-R

HCP0805 = Product code and size

XXX = Inductance value in uH, R = decimal point,

If no R is present then last character equals number of zeroes

-R suffix indicates RoHS compliant

Dimensions (mm)

Part marking:HCP0805, XXX= Inductance value in uH, R=decimal point,

If no R is present then last character equals number of zeros

wwllyy = date code, R = revision level

Tolerances are ±0.25 millimeters unless stated otherwise

PCB tolerances are ±0.1 millimeters unless stated otherwise

DCR measured from point “a” to point “b”

Do not route traces or vias underneath the inductor
