Note1. Measurement frequency of Inductance value : at 100kHz

Note2. Measurement ambient temperature of L, DCR and IDC : at 25°C

Note3. The rated current indicates the current when the inductance decreases to 65% over of it’s

nominal value or D.C. current when the temperature rising

Δt=30°C lower, whichever is lower

Note4. Inductance tolerance: N: ±30% ; M: ±20%
