Weight 0.33 – 0.38 g Ambient temperature –40°C to +85°C with Irms current, +85°C to +125°C with derated current Storage temperature Component: –55°C to +125°C. Tape and reel packaging: –40°C to +80°C Resistance to soldering heat Max three 40 second reflows at +260°C, parts cooled to room temperature between cycles Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C / 85% relative humidity) Packaging 500/7″ reel; Plastic tape: 16 mm wide, 0.3 mm thick, 12 mm pocket spacing, 3.1 mm pocket depth PCB washing Only pure water or alcohol recommended Inductance2 DCR max SRF typ3 Isat (A)4 Irms (A) 5 Part number1 ±20% (µH) (Ohms) (MHz) 10% drop 20% drop 30% drop 20°C rise 40°C rise 1. When ordering, please specify termination and testing codes: ST511PNA104MLZ 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). Testing: Z = COTS H = Screening per Coilcraft CP-SA-10001 2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/ HP 4263B LCR meter or equivalent. 3. SRF measured using Agilent/HP 4191A or equilvalent. 4. DC current at which the inductance drops the specified amount from its value without current. 5. Current that causes the specified temperature rise from 25°C ambient. 6. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering. ■ 6.1 × 6.1 mm footprint; 3.2 mm high shielded inductors ■ Low DCR and excellent current handling
