| Document 688-1 Power Inductor - HA3808-AL For TI TPS6211X 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 -40C to +125C. The part can be operated without damage as long as the part (ambient temperature plus temperature rise due to self heating) does not exceed +165C. Storage temperature Component: -40C to +165C. Packaging: -40C to +80C Resistance to soldering heat Max three 40 second reflows at +260C, parts cooled to room temperature between cycles Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30C / 85% relative humidity) Mean Time Between Failures (MTBF) 26,315,789 hours Packaging 500/7reel; 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 Inductance SRF DCR (mOhm)3 typ4 20%2 (H) typ max (MHz) 6.8 99.0 109 15 Isat (A)5 10% 20% drop drop 4.4 6.9 Irms (A)6 20C 40C rise rise 2.7 3.6 Part number1 HA3808-AL_ 0.276 0,02 7,00 0,50 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 25C.
