1) DCRs (DC resistances) are maximums @20°C.
2) Total current rating (IDC + IAC)
4) DC (Direct Current) current applied to produce a typical 30°C temperature rise.
5) DC (Direct Current) current applied to produce a typical 40°C temperature rise.
6) Suffix of M = ±20%
3) DC (Direct Current) current applied to produce a typical 10% drop in nominal inductance.
