1. Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.25Vrms, 0.0Adc @ 25°C 

   4. Isat: Peak current for approximately 30% rolloff at +25°C 

   5. K-factor: Used to determine Bp-p for core loss (see graph). 

2. Full Load Inductance (FLL) Test Parameters: 100kHz, 0.25Vrms, Isat @ 25°C. 

   - Bp-p = K * L * ∆I. Bp-p:(Gauss), K: (K-factor from table), 

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. -R suffix = RoHS compliant 

   - L: (Inductance in µH), ∆I (peak-to-peak ripple current in Amps). 

   6. Part Number Definition: HCM1103-xxx-R 

HCM1103 = Product code and size xxx= Inductance value in µH, R = decimal point, if no R is present then third character = number of zeros.
