Flat Wire Power Inductor
For Maxim
MAX5051 Controller IC
Designed for Maxim’s MAX5051 Power Supply Controller, the
A9860­‑B offers exceptional electrical performance.
Flat wire windings offers extremely low DC resistance and high
saturation current ratings. The flat core provides excellent heat
dissipation.
Core material Ferrite
Terminations Tin-silver over copper
Weight 11.4 g
Ambient temperature –40°C to +85°C with (40°C rise) Irms current.
Maximum part temperature +125°C (ambient + temp rise). Derating.
Storage temperature Component: –40°C to +125°C.
Tape and reel packaging: –40°C to +80°C
Resistance to soldering heat Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85% relative humidity)
Failures in Time (FIT) / Mean Time Between Failures (MTBF)
38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332
Packaging 200/13″ reel; Plastic tape: 44 mm wide, 0.4 mm thick,
32 mm pocket spacing, 9.6 mm pocket depth
PCB washing Tested to MIL-STD-202 Method 215 plus an additional
aqueous wash. See Doc787_PCB_Washing.pdf.

1. Please specify termination and packaging codes:
A9860-BD
Packaging:D= 13″ machine-ready reel EIA-481 embossed plastic tape
(200 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 D instead.
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft
SMD-D fixture in an Agilent/HP 4284A impedance analyzer.
3. SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMD­‑D test fixture.
4. DC current at which the inductance drops 10% (typ) from its value
without current. Click for temperature derating information.
5. Current that causes a 40°C rise from 25°C ambient. This information is
for reference only and does not represent absolute maximum ratings.
