BRN BLK GRN

1) Tested at 100kHz, 100mVrms @20°C

6) Current applied to produce a typical 15°C temperature rise from nominal inductance.

2) DCRs (DC resistances) are maximums @20°C.

7) Current applied to produce a typical 40°C temperature rise from nominal inductance.

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.
