1360 POWER INDUCTORS Power Inductors for Critical Applications ST598PTA ■ Exceptionally high current carrying capability (up to 43 Amps) and very low DC resistance ■ Magnetic shielding allows high density mounting; flat wire winding keeps the overall height to just 6 mm Core material Ferrite Terminations Terminals 1 and 2: Tin-silver over tin over nickel over phos bronze; Terminal 3: Matte tin over nickel over phos bronze. Other terminations available at additional cost. Weight 2.6 – 2.8 g Ambient temperature –55°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 per 13″ reel; Plastic tape: 24 mm wide, 0.4 mm thick, 16 mm pocket spacing, 6.6 mm pocket depth Inductance2 Part number1 ±10% (µH) DCR (mOhm)3 typ max SRF (MHz) min typ 4 Isat (A)5 Irms (A)6 10% drop 20% drop 30% drop 20°C rise 40°C rise ST598PTA331KLZ 0.33 0.770.85 140200 36 41 43 13.0 16.9 ST598PTA651KLZ 0.65 0.770.85 112160 23 27 28 13.0 16.9 ST598PTA102KLZ 1.02.36 2.60 52.5 75.0 3233 33.59.5 13.0 ST598PTA182KLZ 1.8 2.36 2.60 35.050.0 17 19 20 9.5 13.0 ST598PTA272KLZ 2.7 2.36 2.60 29.442.0 12 13 14 9.5 13.0 ST598PTA402KLZ 4.0 5.50 6.05 23.834.0 11 12 13 7.1 9.4 ST598PTA472KLZ 4.7 5.50 6.0522.4 32.0 9.511 12 7.1 9.4 ST598PTA602KLZ 6.05.50 6.05 19.6 28.0 8.0 9.09.57.1 9.4 ST598PTA802KLZ 8.09.83 10.81 18.2 26.0 7.5 8.59.05.5 7.6 ST598PTA103KLZ 10 9.8310.81 16.8 24.0 6.2 7.0 7.5 4.4 7.2 1.

ST598PTA103KLZ Termination: L=Terminals 1 and 2: Tin-silver over tin over nickel over phos bronze; Terminal 3: Matte tin over nickel over phos bronze Special order, added cost: T = All terminals: copper (95.5/4/0.5) over tin over nickel over phos bronze or S = All terminals: non-RoHS tin-lead (63/37) over tin over nickel over phos bronze. Testing:Z =COTS H=Screening per Coilcraft CP-SA-10001 N =Screening per Coilcraft CP-SA-10004 2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A or equivalent. 3. DCR measured on a micro-ohmmeter. 4. SRF measured using an Agilent/HP 8753D network analyzer. 5. Typical DC current at which the inductance drops the specified amount from its value without current. 6. Typical current that causes a the specified temperature rise from 25°C ambient. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
