1. Open Circuit Inductance (OCL) Test Parameters: 100kHz, 1.0Vrms, 0.0Adc, @ +25°C
2. Irms: DC current for an approximate DT 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 155°C
under worst case operating conditions verified in the end application.
3. Peak current for approximately 15% rolloff @+20°C
4. Peak current for approximately 30% rolloff @+20°C
5. Applied Volt-Time product (V-μs) across the inductor. This value represents the applied V-μs at operating
frequency necessary to generate additional core loss which contributes to the 40°C temperature rise.
De-rating of the I
rms
is required to prevent excessive temperature rise. The 100% V-us rating is
equivalent to a ripple current Ip-p of 20% of Isat (30% rolloff option).
6. Part number definition: HC8LP-XXX-R
HC8LP = Product code and size
XXX = Inductance value in uH. R = Decimal point. If no R is present then last character equals
number of zeros
-R suffix indicates RoHS compliant
