BRN BLK GRN
1) Tested at 100kHz, 100mVrms @20°C
2) DCRs (DC resistances) are maximums @20°C.
3) DC (Direct Current) current applied to produce a typical 10% drop in inductance.
4) Suffix of M=20%
5) Current applied to produce a typical 30°C temperature rise from nominal inductance.
6) Current applied to produce a typical 15°C temperature rise from nominal inductance.
7) Current applied to produce a typical 40°C temperature rise from nominal inductance.
