Please specify tolerance, termination and packaging codes: DO3308P-105MLD Tolerance: M = 20% K = 10% Termination: L = RoHS compliant gold over nickel over phos bronze. 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 100 kHz, 0.1 Vrms, 0 Adc. 3. Tolerances in bold are stocked for immediate shipment 4. DC current at which inductance drops 10% (typ) from its value without current. 5. Current that causes a 40°C temperature rise from 25°C ambient. 6. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
