Power Inductor – HA3808-AL ForTITPS6211X
Step-Down Converters
• Designed for Texas Instruments TPS6211X 1.5A, 17-Vin
1 MHz Step-Down Converters with LBI and PG functions.
• High current, magnetically shielded power inductor
• Soft saturation makes them ideal for VRM/VRD applications
Terminations RoHS compliant matte tin over nickel over copper.
Weight 0.52 g
Ambient temperature –40°C to +125°C. The part can be operated
without damage as long as the part (ambient temperature plus
temperature rise due to self heating) does not exceed +165°C.
Storage temperature Component: –40°C to +165°C.
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)
Mean Time Between Failures (MTBF) 26,315,789 hours
Packaging 500/7″reel; 2500/13″ reel Plastic tape: 16 mm wide,
0.35 mm thick, 8 mm pocket spacing, 2.3 mm pocket depth
PCB washing Only pure water or alcohol recommended

1. When ordering, please specify packaging code:
HA3808-ALC
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic tape
(500 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 (2500 parts per full reel).
2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
3. DCR measured on a micro-ohmmeter.
4. SRF measured using Agilent/HP 4395A or equivalent.
5. DC current at which the inductance drops the specified amount from its value
without current.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
