1. 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 30 °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 155 °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 * ΔI. Bp-p: (Gauss), K: (K-factor from table),
L: (Inductance in μH), ΔI (Peak to peak ripple current in Amps).
6. Part Number Definition: HCM1A1305-xxx-R
HCM1A1305 = 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
