Full Load Inductance (FLL) Test Parameters: 100 kHz, 0.25 V , I , , +25 C 5. K-factor: Used to determine B for core loss (see graph). Bp-p = K * L * I. B : (Gauss), K: (K-factor from table), rms sat p-p p-p 3. I : DC current for an approximate temperature rise of 30 C without core loss. Derating is necessary for AC currents. rms L: (Inductance in H), I (Peak to peak ripple current in Amps). PCB layout, trace thickness and width, air-flow, and proximity of other heat generating components will affect the 6. Part Number Definition: HCM1A0805-xxx-R temperature rise. It is recommended that the temperature of the part not exceed 155 C under worst case operating HCM1A0805 = Product code and size conditions verified in the end application. xxx = inductance value in H, R = decimal point, If no R is present then last character equals number of zeros -R suffix = RoHS compliant Dimensions (mm) Part marking: 1AXXX=automotive grade, XXX=inductance value in uH, R=decimal point. If no R is present then last character equals number of zeros. xxxx=Lot code All soldering surfaces to be coplanar within 0.1 millimeters Tolerances are 0.3 millimeters unless stated otherwise DCR measured from point a to point b Color: Grey Do not route traces or vias underneath the inductor 2 www.eaton.com/electronics xxxx
