When ordering, please specify termination and testing codes: ST432PNA104MLZ Termination: L = RoHS compliant matte tin 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). Note: These inductors have internal parts that contain 100% tin. Testing: Z = COTS H = Screening per Coilcraft CP-SA-10001 Core material Ferrite Terminations RoHS compliant matte tin over nickel over phos bronze. Other terminations available at additional cost. Weight: 81.0 – 87.8 mg 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. Packaging: –55°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 2000/13″ reel; Plastic tape: 12 mm wide, 0.3 mm thick, 8 mm pocket spacing, 2.2 mm pocket depth Inductance2 DCR max SRF typ3 2 Isat (A)4 Irms (A)5 Part number1 ±20% (µH) (Ohms) (MHz) 10% drop 20% drop 30% drop 20°C rise 40°C rise 2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD-A fixture in an Agilent/HP 4263B LCR meter or equivalent. 3. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD -D test fixture. 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. ■ 4 × 4 mm footprint; 2 mm high shielded inductors ■ Low DCR and excellent current handling Power Inductor for Critical Applications ST432PNA
