±361POWERINDUCTORS
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.

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.
