1) Test conditions are 1Vrms and 1.0-8.2µH(7.96MHz), 10-82µH (2.52MHz) 100-1000µH (1kHz).
2) DCRs (DC resistances) are maximums @20°C.
3) DC (Direct Current) current applied to produce a typical 10% drop in inductance or a temperature increase of 40°C whichever is lower. Maximum current is DC + AC.
4) Suffix of J=5%, K=±10%, L=±15%, M=20%, N=+40%-30%
