Open circuit inductance (OCL) test parameters: 100 kHz, 0.25 Vrms, 0.0 Adc, @ +25 °C 2. Full load inductance (FLL) test parameters: 100 kHz, 0.25 Vrms, @ Isat, @ +25 °C 3. Irms: DC current for an approximate temperature 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 that the temperature of the part not exceed +125 °C under worst case operating conditions verified in the end application. 4. Isat: Peak current for approximately 20% rolloff @ +25 °C 5. 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 μH), Δ I (Peak to peak ripple current in Amps). 6. Part Number Definition: HCM0503-xxx-R - HCM0503 = Product code and size - xxx= inductance value in μH, R= decimal point , If no R is present then last character equals number of zeros - -R suffix = RoHS compliant ## **Dimensions (mm)** **==> picture [192 x 9] intentionally omitted <==** **----- Start of picture text -----**
