1. When ordering, please specify
termination
and
testing
codes:
CP312PHA473KLZ
Termination: L
= Silver-palladium-platinum-glass frit.
Special order:
T
= Tin-silver-copper (95.5/4/0.5) or
S
= Tin-lead (63/37).
Testing:
Z
= Unscreened
H
= Group A 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 16197 test
fixture.
4. DCR measured on a micro-ohmmeter and a Coilcraft CCF1010 test
fixture.
5. SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft CCF1232 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.
This information is for reference only and does not represent absolute
maximum ratings.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
