1. When ordering, please specify termination and testing codes:
ST312PHA334KLZ
Termination: L = RoHS compliant silver-palladium-platinum-glass
frit. Special order: T = RoHS tin-silver-copper
(95.5/4/0.5) or S = non-RoHS tin-lead (63/37).
Testing:
Z = COTS
H = Screening per Coilcraft CP-SA-10001
2. Inductance measured at 100 kHz, 0.1 Vrms, using a Coilcraft SMD­‑A
fixture in Agilent/HP 4263B LCR meter.
3. Q measured on an Agilent/HP 4291 with an Agilent/HP 16193 test
fixture.
4. DCR measured on a micro-ohmmeter and a Coilcraft CCF840 test
fixture.
5. SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMD-D test fixture.
6. DC current at which the inductance drops 10% (typ) from its value
without current.
7. Current that causes a 40°C temperature rise from 25°C ambient.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
