1. When ordering, please specify
packaging
code:
SD54-224KLC
Packaging: C
= 7″ machine-ready reel. EIA-481 embossed plastic tape (400 parts per full reel).
B
= Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use code letter C instead.
D
= 13″ machine-ready reel. EIA-481 embossed plastic tape.
Factory order only, not stocked (1500 parts per full reel).
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4284A impedance analyzer or equivalent.
3. SRF measured using Agilent/HP 8753D network analyzer and 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 rise from 25°C ambient.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
