1. When ordering, please specify packaging code:
0201AF-201XKRW
Packaging: W = 7″ machine-ready reel. EIA-481 punched paper
tape (2000 parts per full reel). Quantities less thanfull reel available: in tape (not machine ready) orwith leader and trailer ($25 charge).
U = Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge),
use code letter W instead. Less than full reel. In aneffort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packagingcodes. When ordering, simply change the last letterof your part number from U to W.
2. Inductance measured at 7.9 MHz using a Coilcraft SMD-F test fixture
and Coilcraft-provided correlation pieces with an Agilent/HP 4286
impedance analyzer.
3. SRF measured using Agilent/HP 8753D network analyzer and Coilcraft
SMD­‑D test fixture.
4. DCR measured on Cambridge Technology micro-ohmmeter and aCoilcraft CCF858 test fixture.
5. Current that causes a 15°C temperature rise from 25°C ambient.
Because of their open construction, these parts will not saturate.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
