Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.25 Vrms, 0.0 Adc, +25 C 4. I : Peak current for approximately 20% rolloff +25 C sat 2. Full Load Inductance (FLL) Test Parameters: 100 kHz, 0.25 Vrms, Isat, +25 C 5. K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * I. Bp-p: (Gauss), K: (K-factor from table), 3. I : DC current for an approximate temperature rise of 40 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: HCMA0703-xxx-R temperature rise. It is recommended that the temperature of the part not exceed +125 C under worst case operating HCMA0703 = 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) 2 www.eaton.com/electronics
