- When ordering, please specify termination and testing codes. 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. 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 ■ 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
