Product Specifications
Part Number
Rated Inductance(µH) OCL(1) ± 25% (µH)
Irms(2) Amps
(1) Open circuit inductance test parameters: 100kHz, 0.10V, 0.0Adc, tolerance is ±25%
(2) Irms: DC current for an approximate ΔT 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 150°C under worst case operating conditions verified in the end application.
Isat(3) Amps
DCR(4) Ω Typ.
(3) Isat Amps peak for approximately 30% rolloff @25°C
(4) DCR limits @ 20°C.
