When ordering, please specify termination and packaging codes: DO1813H-473MLD Termination: L = RoHS compliant tin-silver over copper. Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic tape, 1000 parts per full reel. B = Less than full reel. In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter D instead. 2. Inductance tested at 0.25 Vrms, 100 kHz, 0 Adc. 3. DC current at which the inductance drops 30% (typ) from its value without current. 4. Current that causes a 40°C temperature rise from 25°C ambient. 5. Electrical specifications at 25°C.
