1. 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

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.
