Wirewound Ferrite Beads 0402AF (1005)
• Higher performance than other surface mount ferrite
beads in the market
• Ferrite construction and heavy gauge wire for high
current handling
• High impedance across wide bandwidth; up to GHz band
• Extremely low DCR for high current applications
• Eliminates high frequency noise in power supplies or
RF signal isolation applications

1. When ordering, specify tolerance, termination and packaging codes:
Designer’s Kit C397 contains 20 each of all values
Core material Ferrite
Terminations RoHS compliant gold over nickel over silver-palladium-
glass frit. Other terminations available at additional cost.
Weight 0.9 – 1.1 mg
Ambient temperature –40°C to +85°C with Irms current
Maximum part temperature +100°C (ambient + temp rise) Derating.
Storage temperature Component: –40°C to +100°C.
Tape and reel packaging: –40°C to +80°C
0402AF-561XJLW
Tolerance: G = 2% H = 3% J = 5%
(Table shows stock values and tolerances in bold.)
Termination: L = RoHS compliant gold over nickel over silver-palladi-
um-glass frit.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5)
or S = non-RoHS tin-lead (63/37).
Packaging: W= 7″ machine-ready reel. EIA-481 punched paper
tape (2000 parts per full reel).
Resistance to soldering heat Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
Temperature Coefficient of Inductance (TCL) +25 to +150 ppm/°C
Q = 7″ machine-ready reel. EIA-481 punched paper
tape (5000 parts per full reel).
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.
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85% relative humidity)
Failures in Time (FIT) / Mean Time Between Failures (MTBF)
One per billion hours / one billion hours, calculated per Telcordia SR-332
Packaging 2000 or 5000 per 7″ reel. Paper tape: 8 mm wide,
0.68 mm thick, 2 mm pocket spacing
PCB washing Tested to MIL-STD-202 Method 215 plus an additional
aqueous wash. See Doc787_PCB_Washing.pdf.
2. Inductance measured at 7.9 MHz, 0.1 Vrms, using an Agilent/HP
4286A LCR meter or equivalent with a Coilcraft SMD-F test fixture and
Coilcraft-provided correlation pieces.
3. SRF measured using Agilent/HP 8753D network analyzer and Coilcraft
SMD-D test fixture.
4. DCR measured on Cambridge Technology micro-ohmmeter and a
Coilcraft 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. This
information is for reference only and does not represent absolute maxi-
mum ratings. Click for temperature derating information.
